Door Open Holder

Simple Door Holder for CatsThis is a simple door holder I designed for my cats. In its ideal position, it keeps the door open about 10–15 cm, which is just enough for them to pass through comfortably.It's slidable, so you can adjust the opening width to your needs.I printed it with TPU for AMS, so it has a nice snap-fit on the 15 mm thick rim of the door.
