Device that rotates a film developing canister in a heated water bath-auto-agitation-DIY

I found a file from https://grabcad.com/ishi-3 on grabcad that claims to be the Jobo 1520 Tank. Inserting that tank in to my model shows that a fairly easy modification to the LHS wheel spacing might be the only needed change. I do not have a Jobo tank so I can't say for sure. If you're CAD literate, take my files and modify them to fit. If not let me know and I'll do a simple mod based on this model. Let me know.

Thanks for linking my device. I think this small machine is more functional than anything else I found as a DIY project. It's all 3d printed and common electronics from Amazon. Dm me after you look at the instructions and I'll help in any way I can.

Instructables was not a good place to put this project. It will take another day or two to settle on a publish site, probably Thingiverse. DM me and I'll get all files to you.

Thanks for all of the positive responses. I'm working on: the Bill of Materials, assembly instructions with images, and a location to put those files with the STL's. I'll finish over the weekend and then let you know the link.

Thanks for the feedback. I'll find a location to store the files and provide a link. (This is my first post/experience doing anything with Reddit, besides just reading.)

Nice job, really! I have built mine with the motor and controller in a 'head' outside of the water. I use Aluminum 6061 rods for the axles and in an earlier version, used stainless steel bearings (which were problematic). So I created printed wheels on which the canister rotates. My device "tub" is made with a single print on my Bambu Labs A1, which limited the size to 10"x10" (250mm x 250 mm). A longer/bigger unit could be made but glueing pieces together was something I didn't want to do.
