Round Corners Card Size Circuit Symbols.stl

I remixed this model from https://www.thingiverse.com/thing:5255244 . I made it credit card size while adding polarized capacitor, MOSFET and controlled source symbols. Also made a 0.4mm version for using fineliners. I'll later add options for 0.5 and 0.75 ballpoint pens (probably, hopefully).
