This is a front cover for a Texas Nspire model of calculators, in case you scratched, lost, or broke yours. There is also a STEP file of the model here if you want to customize it with logos or anything else your heart desires. Feel free to remix it.

Print it as vertically as possible. It only requires support on the bottom—no need to add support on the pad recesses. The print itself is somewhat flimsy, so if you want to make it more rigid and “mildly” better looking, add fuzzy skin on the front, as shown in the photos. Remember to sand the pad recesses if you are going to add rubber pads. haven't tried TPU but i guess is better than nothing.
