Reusable Staples

Recommended print on 0.1mm layer height or less. 

I would start off printing the base and the "ring - 0mm" (0mm indicates clearance), as this will ensure that a decent amount of force will be needed to overcome the overhang, but depending on the accuracy of your printer, you might need something with a little more clearance, so I have included up to 0.2mm, however, I can't imagine you will need it. If you find that 0mm is somehow still to much, let me know in the comments and I will add a -0.05mm version. I printed them in PLA, but TPU might work as well, so I suppose you might actually want the -0.05mm or more for that.

These model was really easy to make, so I recommend trying it yourself if you have any problems, or see any ways it can be improved upon.
