The file 'Circuit Schematic Stencil 3D Printer Model' is (stl) file type, size is 16.7KB.
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+
