Description

Disclaimer: I made this as a shitpost, I didn't expect it to be particularly useful, and somehow it's been found usable nonetheless. I imagine there are better designs, but thank you for considering mine regardless.

Foregrip I designed, based on some other popular existing designs.

Mounts on picatinny rails.

My goodness, was my print quality awful at the time of this print.

V2: Added filled core version to potentially make this more printable

V3: Didn't like how much gap there was, made the fit a bit wobbly IMO, and added a curve for reduced stress concentration

 

Print instructions:

If you're printing V3, I don't think it'll work as a single print (not enough clearance between layers), so you'll have to separate the parts (right click in most slicer software, look through options).

Turns out if you use PLA and 3 wall layers, it'll snap in load-bearing cases, (e.g. nerf springer priming), you'll likely need more.

 

Hardware:

M3x30 (I think? Maybe longer) bolt x2

M3 nut x 2
