Door holder/latch (kierstandhouder) extension

thingiverse

Our apartment came with balcony doors with a latch to keep it open at a fixed width. (this kind of latch is called "kierstandhouder" in Dutch, please let me know in the comments if there's a better English term. "Door latch" or "door holder" doesn't lead to this particular thing) Our cat Elsa likes to spend time outside on the balcony, but I'd like not to open the door every time she wants to go out. Alas the latch isn't long enough to let her go through the opening, so I made this extension to be attached to the original piece. It adds three more slots so the door gap can be wider. The object is made of two 3D-printable objects to attach to the original piece. You'll add four M3 10mm screws and hex nuts.
