KM LU-202 lock screw
Happened to snap in the middle few of them, so i came up with design very similar to original part. Its before any testing and i will add edit in the future how this design is working out in the field.
Hole is 0.3mm larger than screw barrel, but after first test with PET i was sure thats perfect to get it in with no tools with a little resistance, and I wasnt able to get it out without pliers. To make sure it stays in place i will be using acrylic glue.
Design might change depending on how important is rim around screw, if so it will be commented in EDIT section.
