<!-- 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.

I ended up chopping off most of the threads from this. I went waaay overboard and the friction got too much that it couldn't screw in all the way. I also made a mistake that I'm showing here -- the bottom opening thread needs to be accessible by the top inserting thread. Cutting it solved this, but if I were to make it again, I'd fix that.

The original design of this also had little Lyoko Warriors that would move around the outside, but I ended up deciding to simplify it. Maybe someday...

This part isn't very interesting. The music box itself is screwed into those holes, and the threads screw into the top.

Here's the cool part: the base! There is a circle of bearings on the inside that 3D print as one part (even if they're a pain to get the supports out of, oh my god). The center of the "wheel" is where you screw in the crank for the music box. I tried 3D printing the threads, but my printer couldn't get it that fine, which wasn't surprising, so I did it by hand.

This is the music box tube, as generated by the code up there. A PLA 3D print won't last forever (as you can see I have a few extras in there for semie). A more permanent solution would be to make the tube with indents or holes instead of out outcroppings and then put little metal pins in there. Another option would be to resin print it, but, alas, I didn't have access to a resin printer.

This music box didn't have an E!! I was able to but the theme into a key/octave such that the repeating notes could be on two different spots that played the same note, but no E!!! Augh!!! I tried so hard to make it still sound right... definitely sounds better on my computer than on the box. That might have been my fault: the first step to using the tool is to identify all the notes on the music box. My fiancee and I tried our best, but we definitely could have gotten a few wrong. Still, I'm pleased the song was distinguishable at all.

Hey @zhinyart, here's your gift for @code-swap.

Naturally, I went with Jerlita, but Prompt 2 (Jeremie sleeping in places other than his bedroom) also gave me an idea.
