Just a stencil to aid in drawing electrical circuit schematics.

I've designed it so that it's also compatible to use a 0.5 ball point pen. The traces themselves are 1mm wide. With a mechanical pencil the tip has more room to travel, so you might end up 'coloring' it in a tiny bit in some cases. So here is a version with 0.5mm traces -> https://www.thingiverse.com/thing:5255499

And here is a version with 0.75mm traces -> https://www.thingiverse.com/thing:5259972

I've also printed this in PLA+. I am unsure in how flexible 1mm thick standard PLA is compared to PLA+
