Mateminco FW2 Tactical Ring

A tactical ring for the Mateminco FW2 / Astrolux WP4 flashlight/LEP.

There are two versions, one for the 18650 and one for the 18350 tube. I have a bad feeling about the size of the gap between battery tube and tailcap because it depends on the switch assembly. Before printing you might want to check if the model fits for your specific flashlight and adjust the dimensions accordingly (either in the FreeCAD 0.20 model or by adjusting the z scaling).
