Quad Convoy M21A flashlight mount

This will hold four Convoy M21A flashlights to double the throw and quadruple the lumens. It adds redundancy and the ability to run the flashlights at lower output to achieve the same throw with better efficiency.

The tolerances are pretty tight so make sure you have a well tuned printer or sand paper. I printed the two body pieces with PETG and the handle with PLA. I printed the body with 4 walls to have enough thickness for the M3 threaded inserts that measure 5 mm in diameter and 4 mm depth. I printed the handle with 6 walls for increased strength at 15% cubic infill. I also rotated the handle 90 degrees and printed it flat with supports so that the layer lines are parallel with the long portions of the handle geometry.

14 mm long bolts for the handle and 10 mm long bolts for the 6 other holes. I also placed small washers between the bolt heads. The bolts on the bottom can be screwed in tight so that they don't hit the surface when you place the light down.
