This was a fun print where you get to utilize different materials, TPU and PLA/PETG. The outside bumper makes for a softer feel when using the pop fidget. Make sure to print the insert before printing the frame.

Assembly

• Press-fit buttons into the case
• If you want to add a TPU bumper, press it on. Add glue if it feels too loose
• No more steps

Bumper

Add an optional bumper to give the fidget a larger overall size. The bumper can be printed separately in TPU and forced on.

Printing

This design includes a TPU gasket which is entirely contained within a rigid (PLA/PETG/ABS) frame. Printing requires either a multi-material printer or pausing the print to insert the pre-printed TPU gasket. 92A TPU is recommended, but harder 95A will work.

Either way

• Print the TPU Gasket with at least 5 perimeter shells
• 92A TPU or softer is recommended
• Print buttons separately from the case

If printing on a multi-material printer

• Turn on the “Interface Shells” so the TPU gasket has a solid base to print on
• If using a wipe tower, set “Wipe Tower Extruder” to your TPU toolhead to create a reliable TPU wall around the wipe tower

If printing on a single-material printer

• Pause the print just before the layer where the case begins to bridge. Insert the TPU gasket so that the top is entirely flush
