WWII M15 Sight Mount

This is a STANAG rail mount using the readily available, surplus WWII M15 quadrant sight, for use on Xproducts Can Cannon T-Shirt Launcher with a flat top upper. Three files are given, a mount and 2 clamps. One clamp is counter bored for use with the thumbscrews listed below and the other has straight-through holes for washers, wingnuts, and/or allthread for attachment. I used PLA with .2 layer height printed upright and it works just fine.

A word of caution, the mounting holes are drawn 90 degrees off from the original mounting hole orientation because it was discovered that the springs on the sight are very strong and as a result cause elongation of the countersunk holes.The sight mounts just fine, you just can't see the degrees of arc. This is just for fun anyway.
