AR9 / AR15 KeyMod Foregrip

This is a KeyMod angled foregrip designed for strength, comfort, and a clean custom look.
The model shown in the photos was printed using PET-CF for the main body and TPU 95A HF for the red insert, giving you a rigid, durable grip with a softer ergonomic feel where your hand actually sits.

It mounts using two KeyMod screws + nuts that match the dimensions in the second image (M4 × 12mm screw + compatible nut).
If your hardware is slightly different, you may need to scale the mounting holes by a small amount. Feel free to contact me if you need help adapting it.

Recommended Materials

• PET-CF → Best durability and rigidity
• PETG-CF / PLA TOUGH → Great alternative, still very strong
• PLA / PLA-Matte → Works fine for lighter use
• TPU 95A → For the insert (adds grip + color accent)

The TPU insert is designed to press-fit into the channel.
For best long-term durability, I recommend adding a small amount of superglue or TPU-friendly adhesive to lock it in place.

Printing Notes

• Model orientation is already optimized for strength.
• Requires minimal supports.
• If you're not using dedicated Support Material, supports sit close to the part—expect to pry them off initially.

Hardware Needed

Uses 2× of the following:

• M4 × 12mm countersunk screw
• Matching KeyMod nut (~5.2mm height)

Fits standard KeyMod slots with no modification.
