Uploaded fixed V2 version

Also included one with a bigger bottom lip that is a bit more rigid

Make sure your bed is level before printing

Rotate this 90° before printing

Printed this with TPU filament (Unsure if ABS / PLA Would work)

Inspired by @zerohealths PLA version (You should check it out!)
I've also included a file that should be usable when printed in PLA / ABS

Depicted are a flex version (white) and the only rigid materiel bumper offered here (red)

If you prefer regular-style cases you can find mine here
