Paintball Airsoft Front Grip with bump structure

Paintball and Airsoft Front Grip Foregrip with bump structure for better handling. Print upside down with support. The support is needed for the rail connection, not for the bumps. So you need just a bit support at the lowest two centimeters of the model. The grip is hollowed but strong with one outer 3 wall perimeter and one inner 3 wall perimeter. Its works for 20mm picatinny/weaver rails (standard for most milsim-paintball or airsoft rifles).

**You will need 1 screw M4x35 and one nut M4 or similar size in imperial to fixate the foregrip at the rail to avoid sliding to the front and back. **

3 walls, 25% support, layer height according to your wish for details. I use 0.1 to 0.15 layer height.
