Sheet thickness gauge
thingiverse
Just a simple little gauge for helping you pick the right sheet out of the pile. Instructions A very handy gauge in the workshop. Make a couple, keep one by the laser cutter and one hanging by the sheet rack. Use the toughest MDF or Masonite board you have. Mine is just 2.5mm and I lose them before I ever break them. Of course you could have drawn this for yourself, but you didn't, did you? So I've saved you the trouble. It's in CorelDRAW because that allows me to preserve the colour mappings for cut/engrave.
