3 Fit gauges

Before designing a mount, I print a thin gauge that carries only the mating features: the hole pattern, a locating edge, the clearances. It goes on the real object and answers one question: do the measured values match the part?

A gauge costs about 4 g of PLA and 15 minutes on the A1. A wrong mount costs hours and a lot more filament. The gauge also fails cheaply in a way you can see: brass showing at one side of a hole tells you which way the value is off.

The A1 adds a fixed start sequence of about 6 minutes to every job (heating, AMS load, purge, vibration check, nozzle wipe, homing, prime line). On a gauge that is close to half the job, so small parts that are ready together share a plate.

Two gauges so far:
