Hold a door open

Door holder to keep a door open a few inches (small enough that a cat can't get in = short stl) or several inches (just large enough for a cat to squeeze in = long stl).

Sized for our door width (~35mm) and latch/striker plates (schlage, indoor).

Printed in a stiffer TPU (harder than ninjaflex), but PLA might work if you're careful about inserting it in the striker plate opening. No supports needed, prints flat on the plate, quick and easy print.
