A coin battery LED case, i was inspired by other designs and decided to make my own because i couldn't change the one i found. This one has a big case which can be a pro or con depending on your needs and the button is pushed against a spring.
For future refinement i want to add a USB slot or similar connector to have a lithium rechargeable coin battery inside be charged from the outside. The case has enough space inside to make it possible i think. For now it features a cr2032 coin compartment with a cap to help the button press the coin while inside.
The case should be screwed together with brass insert at the bottom (m2) and m2 screws from the top. In the future i might add a version that can just be screwed together with m3 screws without inserts.
the battery coin inside resides above a spring which prevents it from connecting with the bottom contact of the led.
There are two versions one for a washer that acts as a connector ( 10mm radius) and one without but with a groove to
