Description

Hand tool for loosening or tightening the castle nut holding the SMA connector to the case on the Quansheng UV-K5(8).

Printed from PETG, I was able to get multiple removals and tightenings before I broke it enough to be useless.  When the nut gets tight, it can be abrupt, and if I'm not careful, the tool will snap.

Supports are already modeled in if orienting correctly for FDM printing.
