ThumbHole ForeGrip for Picatinny Rail

This ThumbHole ForeGrip is based on the Pyrangle v5 design by captainslug (original design). I modified it to use metric hardware and added a two-screw mounting system for a more secure attachment to the Picatinny rail.

This grip is especially useful for spring-loaded Nerf blasters, where extra force is needed to prime the blaster.

Features:

• Stronger attachment – Uses two screws for better stability
• Optimized for metric hardware – No need for imperial screws
• Ergonomic thumbhole design – Provides a comfortable and secure grip

Required hardware:

• 6x M3 x 8mm screws
• 2x M3 x 14mm screws
• 2x M5 x 35mm screws + nuts

Printing tip:
For best results, print "ThumbHole ForeGrip Front" at 0.12mm layer height to avoid the need for supports.
