Eggbot clamping device for engraving (beer) glasses

thingiverse

These things makes the "eggbot redrawn" ready to clamp beer glasses for engraving them. The clamping device itself is no remix, but to clamp glasses with a diameter of up to 95 mm I had to resize some parts of the eggbot. And of course it's easier to find this thing as remix. I also changed the engraver mount of socalbob52, because I guess, there should be more possibility to swing. For the same reason, there is a washer on my mounting screw. That puts more power on the vibration. For the glass mount I used rubber tube of a car windscreen washer with a diameter of 6.5 mm. I recommend to clean the glass with alcohol before clamping to prevent twisting.

I noted, that the pen arm used for engraving is too heavy for fast movements. With this pen arm you can draw on eggs with the maximum speed.
