9mm safety training ammo

thingiverse

safe 9mm training ammo. Take used cartridge cases, push the plastic, a little bit of sanding and you are good to go. Printed 100% infill and 0.1 mm layer without supports. Sanding is very important so it won't stuck in the barrel. Recommend to use bold color to make sure it's not a real bullet and so you could find it on the floor to re-use it.
