I have designed this to be attached to an Ender 3 printer and hooked to octopi for temperature and humidity monitor

Requirements: four 3x10mm short screws(take ones with smaller head)

Steps:

1. Print in position from picture
2. Cut the helper part (along red lines)
3. Fix the cable using parts 2 and 3
4. Slide part 3 over and fix it with screws
