Terrarium corner protector

The glass at the corners of my terrarium broke off, leaving a dangerously sharp edge exposed. I decided to design a simple cover in order to protect my fingers. They have 45° chamfers at the bottom, so you should be sure you can print that steep. I initially planned to print the inside with TPU and the outside with PLA, but the AMS does not (reliably) support TPU, so i just used PLA. The thickness of my glass is 4mm, but you can scale your cover according to the thickness of yours.
