Filament Hole Size Tester

thingiverse

I made this while working on yet another filament clip, and thought it might come in handy. Still unsure what diameter you need to use for a filament hole in your design? Not sure whether your filament is consistently sized across the board? This small block features a series of holes in .05-mm size increments tailored specifically for 1.75mm and 2.85mm filament, making it easy as pie to get the right fit every time.
