Cleaning, updating, and prepping two @prusa3d.com MK3 printers for a couple young makers checking out the hobby for the first time. These don’t have all the bells and whistles of newer machines, but they’re reliable, maintainable, and (most importantly for our beginners) free :) #3dprinting

Two Prusa MK3 printers sitting on a table with completed test prints on the print beds.

Two wooden boxes full of 3D printing supplies including operation manuals, flush cutters, glue sticks, wires, spare parts, and filament.

Completed test print on the print bed of a Prusa MK3 printer.

The test print is a silk magenta colored swatch with the text “TEST” and 6 square steps demonstrating different print heights.

I haven’t purchased a new #3dprinter in years. My little farm of MK3s, MK4s, and the an XL has been too reliable to update. But Prusa finally got me with this announcement of a fully assembled CORE One L+ with 8 color INDX preinstalled. Now to wait for the delivery… youtu.be/guS0BpeI0aQ?...

I finally wrote up a CAD trick I keep reusing: roofs that print without any support. Instead of making the printer cross one wide gap, you stack hexagons, rotate every other one, and shrink them until the opening has closed itself. No more support scars. open.substack.com/pub/thecraft...

Stack, Rotate, Shrink: Surfaces That Print Without Support

Stack polygon extrusions, rotate every other one, shrink them and build up your supportless surface.

Disclosure of AI use is appreciated, thank you! While I have plenty of complaints about what AI is doing to the Internet and... everything, clear and accurate disclosure is helpful and builds trust.

BrailleRAP is an open source DIY Braille embosser. Derived from a 3d printer controller and a bunch of 3d printed parts, BrailleRAP can emboss Braille text in a lot of languages and even emboss vector graphics to build tangible documents like maps, board games, and art representation. #OHWC2026

Glad to see that @davidtobin.bsky.social and @joeltelling.bsky.social continue to bring attention to this. These bills are based on a fundamental misunderstanding of how 3D printers work. They won’t solve the ghost gun issue, waste time/money, & are impossible to implement. youtu.be/5ax9zW0w_gY?...

I don't like posting about politics on this account, but I dislike what's happening even more. Trump's threats are disqualifying whether or not they're "just a joke" or a strategic bluff. While there are few political tools available to limit the executive branch, it's well past time to use them.

Open source hardware is awesome. I had a user on Printables make a feature suggestion to add a list of screw angles instead of just opposing sides and I was able to add and test it fairly quickly.

So much has changed since my last video. When I return, I plan to add a "No AI" disclosure. I can't control what YouTube does post-upload, but my own designs, thumbnails, videos, scripts, & captions are not produced by GenAI. To the extent I can verify, any background music I use will be the same.

It's important to understand that when the CDC recommended removing Thimerosal from the routine vaccination schedule, it wasn't due to strong evidence linking it to autism. It was closer to a tactical concession to anti-vaccine sentiment. Remove the preservative to increase trust. This backfired.

Albert Einstein only recently became too young to apply for a driver's permit. It's certainly a curious way to view historical figures. I could see someone building a "reciprocating modulus age" calculator so you could find out which ancient philosophers are old enough to drink again.

I saw we're doing 2016 throwbacks. On this day 10 years ago, I was making the first prints on a Mendel 90 we built for the "How to build a RepRap 3D printer" class I taught at the Dallas Makerspace. I would have never guessed I'd be making a living working on 3D printers founded by RepRap today.

If the first 3 seconds of a video has a voice-over in generic 3rd person past tense ("The man placed a $20 bill in his shoe"), that video is an instant down vote and skip. One might think the YouTube algorithm would learn I treat AI slop the same way a cat handles tape clinging to its back paw.

I have the same cynicism every time I check unit prices while grocery shopping. It's insulting when a "buy one get one free" deal is placed right next to a larger regularly priced box of the same brand which costs less per ounce than the "deal". It's a tax on those too frazzled to math.
