Since my dice are a hit with my friends, I thought I'd make a dice cup too.
download the file and place a small piece of plywood in the laser
Start the lasing process, you can use the preset settings or use your own best settings.
I didn't glue the top and bottom part with the struts, as they are already quite well fitted. Then I glued the inner wall and the outer wall. It would probably hold even better if everything was glued.
You can now leave the dice cup in its rustic look, or sand it down.
