The Hive - Supportless Dice Tower
ATTENTION: There is a newer and over all better iteration of this model here: The Hive v2 - Supportless Dice Tower
Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5386362.
Is what it says on the title. It is a supportless dice tower for all your dice rolling needs. Can be scaled down by 55.5% for mini dice.
While it is supportless make sure your printer's bridging and overhang printing is up to snuff. The dice towers in my pictures came straight off my Ender 3 Pro's print bed with 0 post processing. Only thing is for d4's make sure you toss them in a little bit because if you place them in gently they will just slide down.
I have included 2 versions of the tower. One with the tray to catch dice and one without depending on what you need.
Have fun!
