Staple, chain link

Detachable staple or chain link with a strong connection

I tried different tolerances of the connecting part for printing the staple, I gave 0.15mm, after printing, the parts must be carefully loosened and moved, even the retaining rings can be difficult at the beginning, but they loosen by rubbing against each other. It also depends on the width of the perimeter of your print, I have with a 0.4 mm nozzle, the perimeter is 0.45 mm.
I tested the resistance - the staple safely carried a 12 kg barbell

WARNING !!! Not suitable for climbing and hanging heavy objects, it is a plastic product
