Fantastic! I used this to child-proof an extension cord. Instead of screws, I made the holes bigger with a drill and then locked it all down with zip ties

Nice design, I love how it keeps the return spring closed yet still easy to pull off. Exactly what I needed as I am always putting these cutters in my pocket and worried it will poke a hole. Printed perfectly with PETG

Really nice design. The click when the cards go in is so satisfying...

Fits perfectly! I love the tight fit. For the Jayo spools that do not seem to work (I have had a couple), I didn't need to do any sanding or adjust the slicer. I took a pair of pliers and squeezed them in, which worked every time. Also, definitely print with no supports as the supports were quite challenging to remove. It prints fine without them
