I have a Logitech "Universal Folio" as the case for my tablet. This uses plastic clips on two corners of the tablet to hold it in place. The clips are not very strong, so the pieces break off over time.

These are replacement clips, with much more material in the corners than the original. The freecad part contains both, which are mirror images of each other. There is also a "folio_bosses" part, which contains a replacement for a broken screw boss in the main folio.

There is a pocket on the bottom, which is used to attach to the PET ends of the elastic straps that hold everything in place. Do not let it put supports there, they are impossible to clean out. Supports are useful underneath the corner, but one of the two that I printed didn't have any. It's ragged under the ceiling, but it still works.

I also needed to replace two of the screw bosses in the main part of the case, which is wht the boss parts are about. I bonded them in with an epoxy labeled for plastic bonding.

FreeCad. I measured the dimensions of the original part with basic tools (ruler, protractor) and got the thickness with a vernier caliper.
