This is a bumper for the Adafruit Bluefruit BLE module. Its meant to be printed using Ninjaflex which stretches so its a bit smaller than the module itself to allow it to cling to the module. This means its likely not to be correctly sized for rigid plastic printing.

I've provided a back to the bumper and a slot just in case you've attached headers and want to access those from the back.
