I made these this year as a thank you gift for our Haunted House cast and crew.
It Uses the standard Cube Gear SCAD setup and the nice parametric pins.
Assembly is a bit tricky, knowing which piece fits where. I'll try to upload some updates to it this month that will help.
As with most gear art.. there's plenty of flat surface to stick down, so I leave it to your own choice how you print it.. but I did these without any raft or support.
