Print in place, parametric shirt cufflinks

Wearing an evening shirt? Who says you can't show your 3D printing passion? Here are some shirt cufflinks to help bring some color to a plain shirt.

The project is print in place and fully parametric. You can change the size and tolerances in the attached Fusion 360 file. As well as add any other top-side décor you would like. I have also exported both designs from the file in multiple tolerance sizes.

For printing, choose the tolerance that works well with your printer. On mine, the small Voron V0.1 gets it right with the 0.2 gaps, while my less than optimally calibrated Ender3 will work well with the 0.5 ones. If not sure what to choose, try the 0.5 one. If it's very loose go to 0.3 or 0.2. If it's just a little bit loose, use 0.4. It's a very fast print anyway, so it's worth trying until you get the right setting.

Be gentle when getting the joints unstuck. Wiggle them with as little force as possible until they move.

You’ll need to print with a filament that does not string. I tried ABS and PLA and they worked well for me. Did not try PET-G, it strings too much for me and will clog the joints. Please report if you have any success with it.

Enjoy!
