I settled on this foregrip design after extensive ergonomic testing. It provides excellent control in C-clamp and vertical grip styles. Reversible according to your preference.
Features:
- 75mm grip height
- 13° sweep angle
- Semi-octagonal grip profile for improved control
- Wrap-around grip texture
- Ergonomic shaping to guide your hand into place
I found these dimensions to be the sweet spot. 13° sweep guides the hand into a consistent C-clamp grip and minimizes wrist strain in a vertical grip. 75mm (2.95") height allows a strong 5-finger grip for most.
Designed for M4x12 flat head screws and standard MLOK T-nuts.
The photo example was printed in PA6-CF20 and painted tan after annealing. PETG/ABS is fine for most applications. The rough texture of fiber-reinforced filaments helps with grip. Basic PLA can work as long as it doesn't get too warm (i.e. airsoft).
Recommended Print Settings
Print upright, flat on its bottom. Fuzzy skin recommended for grip texture.
