A Simple Handstop for my Caliburn pump foregrip

mounts via Picatinny rail.
might also be usable for airsoft or real firearms, but only tested on a Calburn 'nerf' blaster. (temperature and recoil considerations)

Helps keep your hand from slipping when using a 'traditional' or 'thumb-over-bore' hand position

Metric Hardware Required:
1 M5x30mm bolt
1 M5 nut with 8mm wrench flats.

Print in the orientation as provided; no supports needed with a good printer (40degree overhang) but strong bed adhesion is required.
-This unusual orientation was specifically chosen for part strength.

EDIT 3/1/2020: increased the build plate contact area slightly for safer printing
