CQR fore grip with screw top compartment

thingiverse

The owner of this item made some changes, including adding a Picatinny rail and expanding the design. They also added a compartment with a screw-top lid. This project was updated as of October 17th, 2018. The owner used an 80% infill to print this model, but they had to rescale it because the cap wouldn't fit initially. There are currently a few issues where holes don't line up perfectly for two screws that attach to the Picatinny rail. However, the nut will still work for one screw and this problem will be fixed at a later time.
