Strip Clip created for .223 ammo.
Printed @ .20 resolution, 30% Infill, using Sunlu PLA Filament
No supports are required.
I a used 6mm Brim to stabilize the print, since these are so narrow and tall.

UPDATE: Jan28,2021
I changed the recommended Infill from 15% to 30%, not sure why but my first batch at 15% worked fine, but my most recent print of these were too brittle to use, maybe different brand of PLA???
