I have a PrusaSlicer question/bug report. @prusa3d.com 6/24: Saved a .3mf file with "Paint-On Fuzzy Skin" w/ only outer walls fuzzy. Today: PS v 2.9.6 (released 6/25) and slice model, now fuzzy skin in between parts (screenshot). Re-painting fuzzy skin still creates unwanted "fuzz" in middle. 🤷‍♀️

I'm going to revisit some of my "Flat Jacks" from 2022 today. This was a fun project based on the jack-o'-lantern models that my family designed in earlier years. Maybe I will be inspired to make a new one... 🤔 🎃🎃🎃 at Cults3D. @cults3d.bsky.social

Nice meeting Greg from @cookiecad.com at the @makerfaireoc.com last weekend. 😊 I hadn't tried their filament yet, but I love their colors. My daughter picked out a spool of Vanilla Redberry that we took home. We chose a few of my models to print and the filament looks fantastic! 🤍🩷

Some practical #3DPrinting last weekend worked very well in my classroom for a few different activities last week. I have 46 seats this year for my largest class, so my other classes have extra desks. I made some for other teachers too. Model coming soon to Cults3D. @cults3d.bsky.social.

Since my inspiration was sunscreen, I felt compelled to print in bright summer colors. Printed Solid Yellow Bird, Cyan, Safety Orange, & White. I also made a very cute set with filament swaps too! More photos in post at Cults3D: cults3d.com/:4649111 @cults3d.bsky.social @printedsolid.bsky.social

🎉 New Post! I made this "Straight Sword" for a friend's costume. Most of what I found online was too fancy and/or looked unprintable. Easier (and more fun) to design my own! Prints in two parts with single extrusion, and I didn't need glue. At Cults3D. Link in bio & comments. @cults3d.bsky.social

After printing these steering wheels for all 4 of us to play together, they were a little tough to manage on the shelf. We needed a stand! Stand models now included with the original steering wheel design. Check out the post below to see it in action. #3DPrinting @cults3d.bsky.social

New post! 🎉 My son is working on his "Valentine Box" for school this week. We designed these "Arcade Game Parts" for it. After printing, I realized the joystick could be slightly modified for filament swap printing, so I did that too! See comments. STLs: cults3d.com/:4014678 @cults3d.bsky.social

I designed these for an elementary school class project where students' individual models won't physically link together, but they should be connected in groups. They can use these trays for displaying their work to show the relationships. New model at Cults3D. Link in my bio. @cults3d.bsky.social

The other printed parts turned out SO cute, that I guess I am going to have to post them on Cults3D after all! I wasn't planning to do so when I started on this project with my son. The joystick and buttons don't move, but they printed very well! @cults3d.bsky.social

020

Abby Brown @abbymath.bsky.social · 01/02/2026

Unfortunately, the print cracked on one side. It printed this way. My theory is that my @sliceworx.com build plate stuck to the bottom so well that when the print warped, it broke away from itself. I used older, non-high temp filament. Should still work for this project though!

Hi, @geektoybox.com! I mention you in the article (above) as providing inspiration for the technique I used for printing a surface with contours. Your "gradient" prints of the fidget cube gave me the idea for how to easily do this. Thanks!!

Digging through our #Protopasta 50g coil collection, we found 6 coils of "thermochromic" colors. We knew they would be perfect for our handheld fidget valentines! Each coil was just enough for three sets of posts and caps. Middle hearts are Hatchbox color-changing. 🤎💚 @cults3d.bsky.social

2/2 The top surface on this #Protopasta Rose Gold is the softest I have ever felt on a 3D print. It's like cotton. 🤯 I don't know whether it's the filament or my new E3D ObX 500 nozzle or the combination of the two, but WOW! Cults3D: cults3d.com/:615039 @e3donline.bsky.social @cults3d.bsky.social
