UPDATE: After trying to print a lot of these I decided to make a simpler support free design to decrease print time. Some of the chamfer angles have been changed to increase build plate adhesion.

They all work perfectly! I will leave the old STLs up since they lock together so well.

This is an improvement to my previous cable tie designs, I have included 3 different sizes with a better design than before. You can scale them up but I wouldn't downscale them because they can become weak. The smaller cable tie needs a good initial twist to lock but works smoother after that.

Note: PRINT ON SIDE with max perimeter thickness (no infill) for maximum strength. Once you twist it in place it will slightly deform, ensure you twist in same direction when reusing so it maintains its strength.

Print a bunch for all your projects! If you have recommendations for improvement I would love to hear them.
