Wanted a Gasamat sign for the garage and couldn't find one already made.
Printed at 0.2mm layer height, color swap from white to red at layer 11 / 2.20mm, then color swap to black at layer 14 / 2.80mm.
For the more basic sign: printed at 0.2mm layer height, color swap to white at layer 11 / 2.20mm.
