Modkat Flip-compatible Liner Clip

[Modkat](https://modkat.com/products/flip-litter-box) is a brand of well-designed cat litter boxes.

I misplaced one of the clips used to hold the box liner in place on a Modkat Flip, so I made a compatible hook based on measurements.

There are two versions here, one which faithfully reproduces the dimensions of the original, and another that is thinner so that it can be printed without the overhanging part.

The company does sell [replacement hooks](https://modkat.com/collections/replacement-parts/products/flip-clip-and-hooks-pack) for about $4.
