This is a vertical pistol grip and horizontal fore grip all in one designed to fit a standard airsoft M4 length lower rail. If the entire deisng is too large for your printer I have broken it into 3 parts so that you can hook them together with a couple screws and print much easier. I cut the hex holes for the screws to fit a 6/32 machine screw I picked up from the local hardware store. If you want a different screw size, feel free to message me.
The "Sample Test Piece" will let you print a small piece to make sure it fits your rail before printing the entire grip.
