Index Clip for NATO Accessory Rail (Picatinny)

thingiverse

This is an update to my previous Picatinny rail cover designs. This is a single slot cover that should fit multiple rail sizes. Dimensioned from official specs and tested on rails that claim to conform to Picatinny, Weaver and NATO Accessory Rail standards, as well as cheap airsoft knockoff rails. As long as the slot is ~5mm wide and ~3mm deep this should fit snugly. Print on the edge with 1 perimeter wall, no infill and no top or bottom layers at whatever layer height you can get away with. You may be able to use spiral mode / vase mode for slightly faster prints (they print in about a minute as it is). I had best results printing many on a shared raft since there's not a lot of surface area to stick to the build plate, but YMMV. Test prints were in PETG, but given the nature and formation of the part, should be fine in any extruded plastic, including PLA. PLA may melt under direct sun, on a black rifle. These These have not been field-tested.
