We couldn't be more thrilled for another year! The support and creativity we see each year brings us so much joy, and we are incredibly excited to see what this year brings!

<!-- CODESWAP 2025 --> This is for @miracleofdatabase I’ve really been enjoying your Code Lyoko fanfic, Cure Code! It was tough choosing just one scene —there were so many lovely Jerlita moments—, but here’s the one I went with. ☺️ Don’t know if anyone’s interested, but I thought I’d share the line art too!

I completely forgot I didn't post this! This is my @code-swap gift for @semie78 ! I made a rotating tower music box! I'm very proud of how it turned out. I bought a wind up music box online. Then, I designed a base with 3D printed bearings (roughly inspired by these, but fairly modified) that screws into the music box wind up. When the music box rotates, it spins the entire tower. I also made sure that the base unscrews from the top so you can replace any parts as needed. A keen eye may notice that it screws in backwards. Uh... oopsies!

The music box itself plays A World Without Danger (video should have sound, might be kind of quiet)....... kind of. I used this amazing tool and modified this midi to 3D print a new tube for the box. Unfortunately, there are only so many notes on a music box, and I had to sacrifice it being in tune for it working... alas... Many lessons learned, haha.

Was a ton of fun! I love designing and making things. Happy to chat more about the mechanical design with anyone who is interested. Some pictures of the CAD and design thoughts under the cut.
