Small rounded earplug holder with magnetic snap.

The other holders I could find didn't really appeal to me, so I designed my own.

Model is about 40mm x 40mm x 25mm after assembly, with an internal space of 32mm x 25mm x 25mm.

Magnets used come from a Vaperesso pod and measures 2.5mm x 2mm x 7mm. You'll need 4.

Fastener used is a M3x25 button head cap screw with a M3 nut. Use locktite on the nut otherwise the hinge action will work it loose. Alternatively use a nyloc nut, just remember to adjust the screw length accordingly.

File are for one piece, so print two. I've also included the FreeCAD file for anyone wanting to remix.
