Does this kind of dice tower exist?

I don’t know the proper flair for this, but I am looking for a Dice Tower that I can 3d print that allows you to load up dice, then hit a button or pull a lever or something and they would all fall through (preferably something not electronic, more of a mechanical relationship). It is intended for some dramatic flair when needed on big rolls. I tried to design it myself (and I may come back to it eventually, but I just don’t have the time right now) and I just can’t figure it out. Has anyone found anything like this?
