You can cover the QR code on your Ender 3 or CR series printer with this. It should also fit over standard NEMA 17 stepper motors, however you'll likely have to cut a small opening for the electrical plug on 1 side.

Suggest printing with the letters facing up, to keep them clean and keep the front free of support artifacts.

I printed it with TPU however any material should work well. The supports came away cleanly from the interior of the cover, where you can't see the scars anyway.

I spray painted this black and lightly sanded the letters to give it a 2-tone look but obviously there are many ways to accomplish this.
