Working on a project for lasering things like pens or business cards or anything else that would be the same thing over and over.  The laser will engrave something, this thing will turn a platter so the next one is lined up, the laser will engrave it, etc.   I think I already posted a pic of the main part.   Today I made the hub that the platter will sit on.  I plan on having multiple platters made from acrylic, was going to be aluminum but with Xometry going away the inexpensive aluminum is gone too.  I have the acrylic, unfortunately my CO2 laser is too small to do it so I'll prolly have to do the platters on the mill and rotary table (I am pondering YAL - Yet Another Laser, but haven't ordered yet).

All that said, here's the hub.  Still need to drill and tap for the set screw and the 3 studs that will hold the platter.   Excuse the crappy pic! It also has some nics in it from when I parted if off and forgot there's an 8mm hole in the middle and it flew off the back of the lathe. The platter will cover that up.
