Works great!

Printed one large on, and one large one scaled up 125%. Pictured here with old Harbor Freight funnel tray.

Easy print, works great!

The lid on the A1 mini version is better than the original

I was looking for exactly this to stop a cat from opening a screen door. My door configuration required the loop part to be installed further away from the screen, so I modeled a block with a hole for an M3 screw to mount the hook part to the door. I'll post a picture sometime when I'm not feeling lazy.

I've printed several of these, and scaled some to sizes to fit soap pump bottles and a dish sponge. I love the simple design.

I scaled the Z axis to fit the width of my drawer. This model is simple and perfect.
