A basic case for the Square Handheld device. The Belkin is overpriced, and I can't find anything else, so I took that as an opportunity to learn to design and made this. I'm very happy with how it turned out. There's room for refinement, but I'd be mostly nitpicking ergonomics and cutout precision.

It's a bit on the boxy side, but all the corners are rounded off. It fits almost perfectly, and the cutouts are pretty spot on. Don't mind the misplaced USB-C port in the rainbow TPU pictures that I extended with a trusty razor blade: it's fixed in v1.1 pictured in yellow.

I recommend printing as shown, using tree supports on plate only, which helps keep everything adhered, solid, easy to print, and has the added benefit of a grippy texture on the back after peeling the supports off of everything but the camera bump. Printed in Amolen Rainbow Transparent TPU, 0.6 mm nozzle, 0.3 mm height. Version 1.1 is printed at the same settings in yellow Overture High Speed TPU with painted on fuzzy skin to help add a bit of extra grip on the sides. The rainbow came out great looking, but I slightly prefer the performance of the Overture on this print.

Versions:

v2.1 - Mostly remodeled, cutouts are now more precise and chamfered, extra for the buttons and chip card slot. Not quite perfect, but likely the final version. v1.2 - For some reason, the edge around the screen lost it's rounded-ness in v1.1, so I went back and explicitly added a fillet to round it. v.1.1 - Fixed misaligned USB-C port cutout. Pictured in neon yellow TPU. v1.0 - Original design. Pictured rainbow TPU.
