Saw this guy (link) and started working on duplicating it.
This is what I’ve got so far. Like the post I linked to, I’m struggling with dice getting stuck on the way down. They seem to hit the ceiling at the second step. After some convincing past the second step they still seem to lose their mojo before making their way all the way out. For my second go I’m going to make it taller (more space between the top steps and the ceiling) and make every other step (or something like that) slanted to help the dice along. I’ll also need to make a wall at the bottom to help guide them out the door.
