I have created 2 versions of back screw. You can print version with standard hole and version for ESP32-C3 supermini.

If you print a version with standard hole, generally most of the LEDs should fit.

In case of issues with in-place printed hinge, there is a separated version attached. But give it a little and gentle “wiggle” after printing and it will be fine :)

Following materials has been used in this project (version with ESP32 back screw):
