MEC Powder Bushings

Printed in PLA using just standard print settings. 

I have these numbered according to MEC's bushing sizes, but because everybody's printer prints differently, the actual hole size may differ. You could either adjust your hole horizontal expansion in you slicer to accommodate, or just measure and confirm your powder throws when setting up a new load.

I did my test prints in Overture PLA and switched to Matterhackers poor man PLA for the full set. Both slipped right into the charge bar nicely.
