I actually bought it on Etsy. The guy has some really nice looking light saber designs, so I asked if he had Darth Maul. He designed it for me.
I’m not sure what you mean by guide pins. Is that something like a dowel you put down the center to align all the discs?
I was thinking 1/8 inch, either MDF or acrylic.
Are you slicing it into discs, or the long way, into vertical slices?
