Fix your flop - Quick repair for torn flip-flops

I was getting tired of throwing away flip-flops that have torn through the hole that anchors the strap. Using a bread tag or a similar solution creates an awkward feel because the anchor point no longer fits flush into the hole, making it feel like you're walking with a stone stuck to your shoe. This fix prevents that by still allowing the anchor to sit flush in the shoe.

This print is a quick and easy fix to the problem. It prints in under 5 minutes and slips right onto the shoe!

There are two versions - one is circular, and one is star-shaped, for extra style points.

This model works on a flip-flop with a 5mm "shaft" and a 13 x 3mm "anchor". It is easily scalable in the slicer to fit any other size that you may need. If necessary, you can cut the flip-flop hole slightly larger to account for the part, or you can cut the anchor smaller, but I didn't find that to be necessary in my case, as the flip-flops were pretty pliable. If you're struggling with the size, drop a comment with the dimensions you need and I'll happily modify it for you!

Shaft = The long thin part that goes between your toes.
Anchor = The large, flat cylindrical part at end of shaft.

Print recommendations:

Material - PETG, ASA or TPU - anything stronger than PLA is good. TPU is ideal for getting a nice friction fit and some flexibility, but my prints in PETG worked fine.

Layer height - 0.2mm works perfectly fine, but I recommend 0.12mm for vertical dimensional accuracy.

Infill/Walls - It's too small for any of these settings to have an effect. 

Print orientation - Both face-down and upside down work fine. You will need supports, but the amount of supports is negligible in either direction.

Temperatures - Try printing at a slightly higher temperature than you normally would, in order to get better layer adhesion. The part will wear down over time so more adhesion is always better. 

How to use:

Pretty self-explanatory. Slip the shaft into the groove, then press-fit the anchor into the opening of the part. Then, push the entire part into the flip-flop hole and you're ready to go!
