Here's another highly specific tool that few, if anyone, will need.

After 10 years the switch and cover on my Surefire E1B were worn out. Fortunately, Surefire support is outstanding, and they sent me a new tailcap assembly without question. Unfortunately, the design of the tailcap has changed in the last 10 years, and the current tailcap doesn't match the rest of the flashlight aesthetically.

No problem! I designed a tool that could easily be cut on a CNC mill. Problem is, Techshop went out of business and I don't have a CNC mill.

TO THE PRINTER!!!
