Filament diameter tester

thingiverse

To ensure proper mating of parts, periodically verify ABS filament diameter. After changing rolls, print this object and assess fit. Name the S3G file with the expected diameter for future reference. If the parts are too tight, increase diameter by 0.04mm; if difficult to join but not secure, raise by 0.02mm; if joins then falls apart, lower by 0.02mm. Repeat tests until a perfect fit is achieved, and use that filament diameter for future printing tasks.
