While drawing today's prompt, my 3D printer was working too.
One of the bigger time wastes I have doing these challenges is trying to cut a lot of paper at exact dimensions, having to measure each, and keep things square.
So designed this little thing using #freeCad and while it took a few tweaks - and I will iterate to make it easier to trim multiple cards- it is square and it works
(and yes, it is a messy print, I had my printer tuned, then firmware got updated... )
