Collapsible Dice Tower

thingiverse

A friend of mine asked me to tackle the idea of making a dice tower that collapses down and fits in a box. After weeks of printing and testing, I finally finished my design. I designed the openings to always be about 30mm between flaps and the final opening at the bottom, allowing my MTG life counter dice (the biggest dice I own) to fall through without any issues. The tower is made up of four walls, three of the flaps, and six flap supports. The "p3" and "p4" walls stand for 0.3 and 0.4 mm clearance between the support walls and the T shapes that make up the walls with the flaps on them. While the 0.3mm fits a bit more snugly, I wanted to be sure people could print the tower and use it without much sanding or wearing down the parts. The little support pieces for the flaps only have a 0.1mm clearance, so I use a pair of pliers to force them into place. This works fine for regular dice, but if you use metal dice, I recommend adding a tiny bit of glue to make sure it sticks so the flap doesn't fall out while using it. Lastly, the dice tower comes with a case that has enough room to fit all the parts as well as some dice on top. The box also has enough room to fit the dice tower when it is assembled, allowing the small half of the case to work as a fence to keep the dice from rolling away from you as they fall. Just to help close the box, I added holes for some 7.8mm magnets I got from Home Depot (https://www.homedepot.com/p/MASTER-MAGNETICS-0-3-in-x-0-11-in-Neodymium-Rare-Earth-Magnet-Discs-10-per-Pack-07045HD/202526363). I made the holes big enough so the magnets slide right in, and all you need to do is add a dab of epoxy. UPDATE 1/7: I learned something that wasn't planned but is totally awesome: if you decide you want the tower but don't want to keep your dice with it, you can print two small sides of the box and the parts of the tower will fit perfectly inside! UPDATE 2/12: To be clear, the parts (for version 1) you will need are: * 1 x side 1 * 1 x side 2 * 3 x flappers * 6 x flapper supports * 2 x support walls, either p3 or p4 (0.3mm or 0.4mm tolerance slots for parts to slide into) * The box halves are up to you UPDATE 3/17: I made two new walls to use: an alternate version of the "side 1" and "side 2" pieces, where the flap falls down into a slot rather than placing the flap in its home and pressing the support into place. (I was asked to design this part, but since I also designed the v2 of the sides, I have not personally tested it.) I also added a version 2 of both "side 1" and "side 2" with print-in-place flaps! They have a piece of support underneath each that needs to be snapped apart before they'll move, but this way it removes the need to print the flap supports! So, to be clear with the version 2 of side 1 & 2, you need: * 1 x side 1 v2 * 1 x side 2 v2 * 2 x support walls, either p3 or p4 (0.3mm or 0.4mm tolerance slots for parts to slide into) * The box halves are up to you
