This simple design holds a dog crate door open, allowing your pet to have free access to their space without locking them in. This clip is a snug snap-on fit that doesn't slide or rattle and can be pressed flat against the door when not in use. The thumb ramp adds adequate separation force to make it easy to disengage.

I recommend printing in PETG for mild flexibility and impact resistance, a PLA latch will work, but is more likely to wear out or break when snapping onto the bars. Printed with 5 perimeters to make a strong durable print.
