Logic Gates

Logic gates.
As they are, they have a circular (r=7mm,h=1.5mm) space on the top, but the scad file is included, so just modify them to your needs.
(I want to put them on a whiteboard, and that hole fits a disc magnet.)

Update: I realized that the filled ones have a few issues while printing. I will fix the openscad file as soon as I get to it
