The model is designed to house an apple AirTag, with a screw in top (cap) and an o-ring for water tightness.

I'm also including the fusion 360 file for anyone to make an easy remix there.

Printing recommendations

• Printing the base and top (cap) on any regular PLA should be enough.
• O-ring should be printed on TPU or any other elastic material.
• slow speeds.
• low layer height so that the screwing pattern prints nicely.
• no support needed. But you can add some support for the base offset where the double sided tape goes.

Other instructions

• use 1mm double sided tape at the base offset to stick it to any surface
• IMPORTANT: when inserting the AirTag do it on the top (cap) with the metal part facing outward. This way you can easily remove it whenever you need.
• ALSO IMPORTANT: Don't stick it to the top or bottom parts of the board as it may get detached when putting your board in a gondola side carrier. Its better to stick it on the inside middle section right next to either of the bindings.
