UPDATE 2024/05/31: Added an improved version of the screw and insert for a better fitment of the threads, also .3mf files

Print Instructions:
Everything can be printed in place without supports with at least 10% infill. PLA works well, for more strength print with at least 3 walls. Just take care of the M14 thread insert and the screw by using 0.12 or 0.16 resolution and maybe a lower printing speed to make both parts fit perfectly.
Assembling:
Enjoy!
