parametric .40 s&w dummy round

Training dummy round in cal 40 s&w. I've tested and printed several ammounts and i used it commonly during my trainings to simulate jams. It chambers perfect and it can be loaded in any magazine 40 cal.
I designed this dummy round with a hole where the primer goes, so the firing pin wont touch the plastic , yes you can fire the gun with no compromises.
I have tested this model on my glock 22 gen 4 cal 40 with no issues.

Build time: 59 mins
Filament lenght: 613 mm
Plastic Weight : 1.85 g
Material cost : 0.08
PLA+

Thanks, Enjoy!
