Rollup Dice Box Large Dice (Large)

This is a larger version of the 3D Printy Rollup Dice Box (large) that can hold 20mm and 22mm dice, and the dice tower won't struggle with the large dice size. I strongly recommend you avoid printing this with any silk, matte, or other brittle filaments. PLA, PLA+, PETG, PETG+, ASA, ABS, and ABS+ filaments should all work just fine. Also because 3d Printy already has their instructions written out quite clearly I will just copy paste them here.

Bin Options

• Plain  - No dividers. This can be used with crafting foam to make your own tray layouts.
• Hexagonal - Holds up to seven dice.
• Hexagonal Cats - Holds up to seven dice, but with cats in two of the bins.
• Circle - Holds up to seven dice.
• Square - Holds up to seven dice.

Other Options

• Use “Short Tab” start bins if you want the container to be able to sit flat while vertical. Warning: this does make the box slightly more difficult to open.
• Use “Mix Tab” start bins if you want the container to be able to sit flat while vertical but still has a longer tab on top.

Printing

• Most standard PLA formulations are fine, but avoid brittle silk and matte PLAs.
• Print one start bin, one end bin, and four middle bins.
• All parts can be printed without supports.
• Add a brim if you experience curling issues on tight corners.
• Swap the filament color mid-print for a dual color effect.

Assembly

• Glue eight 6x3mm magnets into the start and end bins. Make sure the magnets are oriented so that they pull the bins together.
• Use a scrap of unprinted 1.75mm filament to connect all six bins together.
• Align the top of the core with the bottom - make sure that the two ends are correctly rotated.
• Firmly press the core top into the core bottom. These parts are a very tight fit and may require a lot of force to close. To avoid damaging either part, apply pressure only near the center of the top and bottom.
   

If the instructions are still unclear there is an assembly video over on the 3D Printy page for their version of this box. If there are any fitment issues with this leave me a message. I have not included the dice trays, but I will make some if enough people ask for them.
