About this model

Print in place, snap shut catch to keep doors open or closed. Feel free to scale up or down to suit your application, at 100% the screw holes are 5.5mm diameter. This is a really big and quite strong clip, if you need something smaller please use my other design. You will also notice the render is slightly different then the 3D file, I removed some material to make the snap action smoother. [](
