HIT Target Impact Indicator mount

This is a 3d printed mount for the Hornady HIT Target Impact Indicator. It prints in three parts and requires an adhesive-backed mirror and two 0.47 in. Neodymium rare-earth magnets (from a big box store) for use. Once printed, put the magnets into the holders and slide on the front, insert the HIT into the box, then attach a mirror to the 45 degree arm and slide it on to the back. The magnets will hold the target on the back of a steel target, with the mirror projecting over the top. Stray rounds will no longer be able to damage the HIT. I printed this in PLA because I bring my HIT targets inside after every range trip. It's also printed with rather thin parts, because I expect to replace them fairly often.
