Carpet Corner Stiffener

Are the corners of your carpet curling up? Print out 4 of these and using carpet tape, stick them on the underside of your carpet corners. You can squeeze 2 of these onto a 200 x 200 bed.

I used PLA, but a stiffer material like ABS would function better. I recommend hex fill for stiffness.

Grooved side up. Put your tape on the side without grooves and stick that to the underside of the carpet.

I got a look at a commercial version and this is way superior.
