Design Requirements

Needed a case to hold my earplugs when traveling

FreeCAD Parameters

Earplug Outer Diameter =19mm
Earplug Depth =25mm
Hole Diameter =14mm
Hole Depth =22mm
Wall Thickness =1.5mm
Cap Overlap =15mm
Tolerance =0.15mm

Printing Setup

Printed with PETG using a .4 mm nozzle and no supports.

First Impressions

The cap fit really loose, had to use 3 layers of packing tape to get it to fit nicely, if I were to print it again I would decrease the tolerances so the packing tape wasn't required. The clear PETG I printed it with works well, it's easy to see if the case has plugs in it or not.
