I recently took a chance on a table saw from the thrift store which was missing the safety key. After rigging it temporarily to ensure it worked I needed to get a new key. At 15 bucks, I figured there was a way to make one. If only there was a machine that converts beams of light into magic :). I found an STL someone had posted on Thingiverse, exported a profile and then cut from some scrap acrylic I had. Works perfectly.
I’m curious what you guys have used your Glowforge to fix.
