supportless cat scratcher cardboard strip cutter

a friend wanted a cardboard strip cutter to make cat scratchers, I found one here but it needed supports to be printed so I decided to modify (or rather redesign) it so it can be printed with no supports. This one requires a threaded insert (I used M4) to not rely on threads against plastic.

Cut strip size is 43mm, it's easily adjustable by changing cardboardCutSize variable. If there's interest I could upload several sizes.

2024-11-07: Added model for thicker cardboard. You can adjust the thickness of the cutting hole using cuttingHoleSize parameter.

Print in original orientation, I used 3 perimeters with 15% infill for some stability.

I also parametrized my model, here's the link

Pretty much redesigned from scratch with same ideas. Made parametric CAD and removed the need for supports. 

Added M4 Threaded insert and bolt for durability.
