Day 2 of @3dprintopia.bsky.social is in the books. With the power fixed and me having a chance to catch up on all the things I wasn't prepared for we at least got most of the top front row running. Sorry to anyone I couldn't give enough time to, especially on my hectic day one.

All setup for this year's @3dprintopia.bsky.social Be sure to come say hi and check out the printers.

RainMotorsports @rainmotorsports.com · 21/09/2025

Want to see the printers I've posted these last 19 days. See all of these and more ready to print live at @3DPrintopia less than 7 days from now. The only real limit is how much electricity I can pump into the booth!

RainMotorsports @rainmotorsports.com · 19/09/2025

Countdown to @3dprintopia.bsky.social Day 19. I am currently on a plane flying back with this Makergear M2 Rev A that has had a 24v, Rambo 1.3 & Dual Extruder Upgrade in its lifetime. I have to imagine it's the last printer I acquire before the event so group photos, booth info is next up.

RainMotorsports @rainmotorsports.com · 19/09/2025

Countdown to @3dprintopia.bsky.social Day 18. The latest in my collection is this Lulzbot Taz 6. Not something I was after but its nice to have next to the 4 & 5. A Mini would probably round out this end of the collection. But before I leave Hawaii I'm probably buying another old printer.

022

RainMotorsports @rainmotorsports.com · 18/09/2025

Countdown to @3dprintopia.bsky.social Day 17 still Hawaii Standard Time. My fourth and final Makerbot Replicator 1 is this single toolhead model I bought for $31. The others are duals so this mixes things up at an inexpensive price. Long term parts donors are also important.

022

RainMotorsports @rainmotorsports.com · 17/09/2025

Countdown to @3dprintopia.bsky.social Day 16. Later than usual post it's still only 7pm in Hawaii. This Printrbot Plus is my third of the brand. Like the simple it has a Rev D board. I picked this up in Front Royal Virginia and got it printing recently.

033

RainMotorsports @rainmotorsports.com · 16/09/2025

Countdown to @3dprintopia.bsky.social Day 15. The second Printrbot in the collection was this Simple 2014 model. The previous owner changed the line drive to a belt drive. Seems to have a bit of issues with Z binding/wobble. The RevD is a tight squeeze but can run Marlin 2.1.x or Klipper.

053

RainMotorsports @rainmotorsports.com · 15/09/2025

Countdown to @3dprintopia.bsky.social Day 14. On my way home from buying a Monoprice Mini Delta the seller informed me he probably should have given me this Solidoodle 2. Weeks later I went back for it. Its currently a project. I've added a 24v heater but it'll be a mess at the show.

033

RainMotorsports @rainmotorsports.com · 14/09/2025

Countdown to @3dprintopia.bsky.social Day 13. This Makergear M2 is quite a bit newer than the original 2012 version. But its a fun one for people who have never seen a bed slinger that raises on Z. I moved this printer during an office move last year but later got it during the decommission

112

RainMotorsports @rainmotorsports.com · 13/09/2025

Countdown to @3dprintopia.bsky.social Day 12. I avoided it for so long but earlier this year I bought my first printrbot. This simple metal came out of Philadelphia for $10 and now runs @marlinfw.org 2.1.3 Beta 3. Banana for scale.

022

RainMotorsports @rainmotorsports.com · 12/09/2025

Countdown to @3dprintopia.bsky.social Day 11. 8th in my collection and 3rd Replicator is the one I rebuilt for someone I met at 3D Printopia in 24. His desire to use the machine helped me learn to put @marlinfw.org on it. In the end we put FlashForge MK10 toolheads in it with part cooling.

112

RainMotorsports @rainmotorsports.com · 11/09/2025

Countdown to @3dprintopia.bsky.social Day 10. 7th in my collection & 2nd Replicator. Original owner Nick Margarone from the Brick Drone Kickstarter used it to start a company. I flew this back from Florida disassembled in my carry-on. It now runs Marlin 2.1.2.5.

RainMotorsports @rainmotorsports.com · 10/09/2025

Countdown to @3dprintopia.bsky.social Day 9. The 6th classic in my collection and second Ultimaker is this UMO+. The previous owner was gifted it by Ultimaker at an event. The UMO was a great printer for it's time and the heated bed is a must have upgrade that the UMO+ came with stock.

022

RainMotorsports @rainmotorsports.com · 09/09/2025

Countdown to @3dprintopia.bsky.social Day 8. This Makerbot Thing-O-Matic just arrived. Includes the belted automated build plate. Everything seems functional. I tore it down, cleaned it up and all that's needed is a bit of cable wrap.

023

RainMotorsports @rainmotorsports.com · 08/09/2025

Countdown to @3dprintopia.bsky.social Day 7. The 5th classic in my collection a @lulzbot3d.bsky.social Taz4 was brought to last year's event by MattsPrintables from a person in the Voron discord. I have seen gone through this printer but I dont seem to have taken many pics. Dual Budaschnozzles!

053

RainMotorsports @rainmotorsports.com · 07/09/2025

Countdown to @3dprintopia.bsky.social Day 6 I'm late again. The 4th in my collection of classics is the @e3donline.bsky.social BigBox. Seen last year with Georgia and David who later put me in touch with designer Greg Holloway. It now runs and hopefully will spit out some makerchips for me.

032

RainMotorsports @rainmotorsports.com · 06/09/2025

Countdown to @3dprintopia.bsky.social Day 5. The third classic in the collection was a Lulzbot Taz 5 with dual extruder. I don't seem to have any good shots and it's in my cube waiting for the event. So here's a photo of the extruder.

012

RainMotorsports @rainmotorsports.com · 05/09/2025

Countdown to @3dprintopia.bsky.social Day 4, posting a bit late. This near mint Makerbot Replicator was the second classic in my collection. This was at the show last year and triggered some events that caused my collection to grow massively this following year.

012

RainMotorsports @rainmotorsports.com · 04/09/2025

Countdown to @3dprintopia.bsky.social Day 3. This Ultimaker Original was the first classic in my collection. Its running Klipper with inputshaping at 10k accel on the stock MCU. To make life easier I added a spring steel sheet and with a probe in the second hotend slot.

001

RainMotorsports @rainmotorsports.com · 03/09/2025

Countdown to @3dprintopia.bsky.social Day 2. Wait is that ANOTHER Makerbot cupcake? This one needs a bed but it looks like it will also be printing at the event! MK5 Extruder this time. Mechanical relay on the heater goes click clack all print long!

012

RainMotorsports @rainmotorsports.com · 02/09/2025

Count down to @3dprintopia.bsky.social 2025. Day 1 we have a working 2010 MakerBot Cupcake CNC with MK4 extruder that will be at the event and hopefully printing the entire time. Come see this and more at the This Old 3D Printer booth. #3DPrinting

042

RainMotorsports @rainmotorsports.com · 10/07/2025

Y AXIS is mirrored after flashing firmware but can we pretend for a minute the MakerBot Cupcake is printing well? .28 layer height 215 motor pwm at 30 mm/s Stopping the hotend side to side movement may improve this quite a bit. #3dprinting

041

RainMotorsports @rainmotorsports.com · 07/07/2025

Could this be the first time a Voron test cube was printed on a MakerBot cupcake? Hopes are high this will be printing during @3dprintopia.bsky.social

041

RainMotorsports @rainmotorsports.com · 07/07/2025

The Makerbot Cupcake CNC is running on all axis now after temporarily swapping the driver board for a bread board. Thanks to @peraf191.bsky.social for the suggestions and info. Repair parts are in the mail though. Printing soon. @3dprintopia.bsky.social after that.

121

RainMotorsports @rainmotorsports.com · 06/07/2025

Updated photo of the printers you can expect to see at my booth for @3dprintopia.bsky.social They should all be working. Most with Marlin 2.1.3b3+ or Klipper. Mostly limited to the power available. Cupcake shows signs that it will work once I fix the driver I blew up.

021

RainMotorsports @rainmotorsports.com · 06/07/2025

Big news. I finally added a Makerbot Cupcake CNC to the collection and it will be with the rest @3dprintopia.bsky.social This may actually be printing at the event. It turns out it was way better of than we thought until I fried a driver!

052

RainMotorsports @rainmotorsports.com · 30/05/2025

Starting a little planning for @3dprintopia.bsky.social Should have 12 printers crammed in. MK0 is placeholdered by a mk2. Delta to the back right of the printrbot. Leaves room for 2 more. Should have a Solidoodle 2 soon. We have more replicators & projects as the last possible slot.

040

RainMotorsports @rainmotorsports.com · 19/05/2025

Hey maybe there is a chance the Printrbot printrboard isn't dead?. I got one home out of it before the board stop responding and it seemed to have done a thermal runaway on any other tried. Flashed firmware and it's respond again. Check the mosfet output seeing 40millivolt.

RainMotorsports @rainmotorsports.com · 18/05/2025

The rebuild on the Prusa i3 Rework (MK0 era Fork) hit a milestone last night. Assembled the Reprap MK2B PCB bed and tested to 100C. The owner plans on loaning it back to me for the @3dprintopia.bsky.social display. Bunch of small stuff left but the 2.85 toolhead is the major work left.

000

RainMotorsports @rainmotorsports.com · 22/04/2025

No MMU? No problem. My wife was going to paint these from a solid color print. I grabbed old reliable off my desk from work as it's easy to change filament on quickly. 25 filament changes taking an additional 21 minutes over the original print time estimate.

RainMotorsports @rainmotorsports.com · 02/04/2025

Oh man. I forgot that yesterday was the end of support for the Ultimaker Original+. 10+ years of support for the plywood wonder. #3DPrinting #Ultimaker

071

RainMotorsports @rainmotorsports.com · 28/03/2025

3D Printers Assemble! Another round of dusting off and working on Stock, #Marlin, & #Klipper in preparation for my latest project I hope to show @3dprintopia.bsky.social this year. With mottos like "Not a Museum" and "Hey we're still using that" I'm here to bring this machines into 2025 and beyond!

150

RainMotorsports @rainmotorsports.com · 21/03/2025

I may have done it again. This one has some history. Owned by Nick from the Brick Drone Kickstarter. This machine apparently had something to do with the work on that.

140

RainMotorsports @rainmotorsports.com · 17/03/2025

Ultimaker Original Plus keeping the spiders awake this evening. First print since I bought this one Saturday.

010

RainMotorsports @rainmotorsports.com · 15/03/2025

The new addition is on the shelf. Reran the wiring but need to extend the thermistor. Screen is off my UMO at the moment as I was looking into replacing the damaged LCD.

150

RainMotorsports @rainmotorsports.com · 14/03/2025

New acquisition. Totally related to something we're cooking up and hoping to show off at @3dprintopia.bsky.social if it gets far enough along. Still need a cupcake and a thingomatic in the collection.

RainMotorsports @rainmotorsports.com · 23/11/2024

Not that I have anything going on, but I figured I would update my handle to my domain. Been on the road for 2 weeks, several days & an extra unplanned state. Haven't gotten any of the usual CAD work I would do on the road or anything else in my spare time. Bringing home more projects too lol

000

RainMotorsports @rainmotorsports.com · 20/11/2024

IBM XT clone and monochrome graphics card. This will be a bit of a challenge to get running. Simple in so many ways but complicated for a modern world.

020

RainMotorsports @rainmotorsports.com · 20/11/2024

My 12-13 year old self would be in heaven right now. I never got to own a K6. Had a pile of Cyrix chips. It's a shame I sold off my VooDoos with the rest of my collection to make room for 3D Printing. Hopefully I can build a new retro rig.

000

RainMotorsports @rainmotorsports.com · 18/11/2024

I'll tell you what probably doesn't get much use anymore on the opposite end. Registers used to have a fill-up function. You could pay inside with card without specifying an amount. Of course you just do this at the pump. But I still wonder I've never witnessed this being used in recent years.

010

RainMotorsports @rainmotorsports.com · 15/11/2024

Having grown up where everything was a different site or app and having to be on 5 at a time just to communicate with friends. The last thing I wanted was to jump ship. But as this reaches critical mass. I supposed here goes nothing.
