Led Lenser T7 Battery Holder

thingiverse

I stumbled upon another battery cage for a Led Lenser T7 on Thingiverse, but unfortunately, the thread was too small and lacked holes to securely screw down the cap. To make matters worse, the button didn't fit properly either. I decided to experiment with printing threads since I wanted to fix my flashlight using the cap from that other design. This thread screws in quite tightly and requires firm guidance because it is prone to cross-threading (my experience confirms this). The thread appears to be an undersized 21x1 metric thread.
