I've designed many dice towers over the years, and I particularly love this one. Here's why:

1. It is perfectly functional, dice do not get stuck
2. It prints in one go, in your typical entry level resin printer
3. It's hinged, so it stows neatly inside a board game box like Monopoly

Here's a vid of it in action:

I have paid meticulous attention to every detail of its design, but I'm still open to feedback. If you found this useful, it would bring me great joy to see your work - so be sure to share. :)

Or, better yet, please feel free to dump a bitcoin or two here:

... include a note to the effect of "Hi 3E8, thanks for the single print hinged dice tower thing... my life has improved five-fold on account of it and please accept this paltry amount in gratitude".

You're welcome! (in advance) :D

Also, feel free to peruse my other submissions which are almost as varied as they are many:

Enjoy!

April 14th, 2020 update: Added a version with offset chevron-shaped baffles so that the dice don't have a chance to fall straight through.

April 19th, 2020 update: I removed all but the final version of the tower with aligned chevron baffles. There have been some minor tweaks that have simply made it that much better. It packs in a standard Catan box and now 'snaps' in the closed and open positions.
