No Crumb Tray: go-nogo gauge

thingiverse

When working with items over half an inch thick and the crumb tray has been taken out, this gauge enables the Glowforge user to position the component precisely at the correct height above the machine's bed. The lower edge is 1.39 inches from the base, while the upper edge stands 1.89 inches from the bottom. By placing the gauge on its foundation, users can freely position their parts anywhere within this range, ensuring the Glowforge focuses correctly.
