A Simple low cost low filament door stop with a small gap to act as a spring.

2 files. 25.5 mm wide and 10mm wide

Normal settings, Print in place, no supports.

I printed with PLA+ at 10% infill. If you need something stiffer, print with a higher infield.

On my P1S at 10% infill the thin door stop printed in about 15 min and only used 3.5 meters (10.3 grams. For me that's a cost of about .10 cents usd.)
