Laser etched rubber stamps
From Bloominglabs
I made some rubber stamps on our laser machine. I went ahead and cut a wood base and turned a nice handle on our wood lathe. Just used some common fast-setting household glue to hold it all together. Note: you do NOT want to use regular rubber from a hobby store. That stuff creates very very bad fumes. This stuff is specially formulated for laser etching, it smells bad but is tolerable.
