This foregrip shares geometry with a few other nerf blaster foregrips. One in particular that only costs $8 that I can never seem to find in stock anywhere. It's a great grip, and by all means you should purchase it and support that company. If you can find one, that is.
This has been modified since I originally posted it, and you can see the differences in some of the pictures. I've added another model orientation, and also removed those pointy bits near the front of the pic rail clamp. Those were a total oversight on my part.
There are two models to choose from depending on what orientation you want to print at. Please select the appropriate model for your intended print orientation, because the horizontal holes are elongated to allow for filament droop in the overhangs. (See pictures)
There are cases to be made for the strength of either orientation, so I will let you decide. After printing and using one, I believe the 45deg model to be the strongest. But I also prefer the ergonomics of the upright model, as it has slightly more material at the top finger groove. That being said, I've printed a few of these now, and even my earlier models have not broken. That's because I've printed everything in PETG, which is my recommended material for this application. If you use PLA, please do not use the grip on a springer.
As you can see in the picture gallery, I have applied 32 pounds of force to this grip with no damage to the grip. I did damage the blaster doing this, which was the only thing preventing me from applying more force. If your grip breaks, your printer isn't tuned well for PETG, your filament is weak, or you printed in the wrong orientation.
Arrange supports for each model as shown in the pictures.
Minimum settings for springers:
0.2 layer height max and 5 walls with a 0.4mm nozzle.
