Filament 3mm tester

A simple printable tester to make sure your own recycled filament has the right diameter for 3D-printing in the Ultimaker original. If the filament is bigger than 3,2 mm it won't fit in the tester and neither through the tube of the Ultimaker. If it's less than 2,6 mm it will fall through to make sure the printer gets enough material.

Let us know how it works for you!
