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.

🎉 New Post! "Squeezer Set" ☀️ My spin on the toothpaste squeezer. Our sunscreen is a tough squeeze this summer and we decided that different widths work well as a set. Now I have little gifts for friends and family this summer too! Model at Cults3D. Link in bio and comments. @cults3d.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

New York Wants to Ctrl+Alt+Delete Your 3D Printer New York’s budget bill proposes mandatory file-scanning “blocking” software for 3D printers and CNC tools. #3dprinting #opensource

the statue of liberty on liberty island, holding a torch and tablet engraved with july iv mdcc lxxvi, framed by blue sky and harbor water, overlaid with a faint “3d” graphic — a symbol of freedom now ironically paired with policy efforts that want to put file scanners and kill switches on general-purpose tools.

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

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

I love the new purges in the @prusa3d.com firmware update on my MK4S printers! They look like little swords with artistic hilts. I almost hate to toss them. Hence the accumulation in my workspace. 😆

Wow! How is it possible that all four colors in the Printed Solid Mystery Box are colors that I don't currently have?! 🤯 A great surprise from the @joeltelling.bsky.social fundraiser for Seattle Children's Hosp.

I made a thing! My "Filament Reminder" is already super helpful for keeping track of which filament was where in my @prusa3d.com XL. I usually unload after a project. Now if I want to load a new color a while later, I can easily see the best tool to use! Link in comments @cults3d.bsky.social.
