This is a small rugged case. Works very well for small items. Was designed to fit my hearing aids. V5 has an extra slot for spare hearing aid batteries. V4 has no slot. Gasket and latches work for both versions. WILL REQUIRE 2 LATCHES for each if you print your own.

Gasket Needs to be printed out of TPU.  3mf file does not have the gasket out of TPU.

Requires 4 2mmx20mm bolts but you can use a piece of filament in place of them if you run a drill through the holes. 

Outside Dimensions are 68.5mm long (2.7") by 56mm wide (2.2") by 40mm deep (1.6").  Inside dimensions are 2.125" by 1.6" by 1" deep.
