Foldable/ Collapsible Dice Tower

Foldable Dice Tower

Requirements

To make this dice tower you need following stuff:

• All the printed parts (see below)

• Roughly 150cm of raw filament (1.75mm diameter) as hinge pins

• (optional but recommended) A few drops of super glue

Print instructions

You need to print one of the following parts: FrontWall, RearWall, ShelfTop, ShelfMiddle, ShelfBottom, Tray

You need to print two each of the following parts: SideWallMainBody, SideWallMainBodyMirrored, SideWallUpperHinge, SideWallLowerHinge

Print them in the following orientation:

• All the side wall parts: flat face on the print bed, bricks looking up

• Front and rear wall: Bricks on the print bed, insides looking up

• Shelves: Look at the bore for the hinge. It's slightly teardrop shaped. Place it so that the point is facing up.

It should print well in PLA without supports. 
Optionally, If you have a multi material printer you can add PETG support to the front and rear wall to make the seams between the bricks slightly nicer. Make sure to choose "support on build plate only" because you don't want support material in the holes for the hinge pins.

Make sure to have a clean build surface with good adhesion. If the corners of the hinges even slightly lift up, the bore gets to squished to insert the hinge pins.

If you have a multicolor setup, I added a Prusa Slicer .3mf file containing all parts, with painted bricks. I also added fuzzy skin on the outside of the tray.

Assembly

Use some raw filament as hinge pins. First add the shelves to the front and rear wall. The top shelf is the shortest one, the bottom shelf is the longest one. The top and middle shelf look symmetric but aren't. Mount them so that the side that was lying on the print bed faces upward (or against the wall if folded). If you put them the wrong way you should be unable to get the hinge pin through, so if you can insert the pin (filament) without problem, you should have the correct orientation. For the bottom shelf the hook looks outward if the shelf is folded up to the wall. Make sure to insert the raw filament all the way to the end of the bores. Cut the filament flush and secure the end with a drop of super glue. Then continue to assemble the side walls. For each wall you need a regular and a mirrored main part and one upper and lower hinge. For the orientation of the hinges look at the pattern of the bricks. Again, use raw filament as hinge pin, cut it flush and secure it with a drop of super glue. In the same manner join the front and rear walls to the side walls.

Usage

To fold the tower, turn it upside down. Usually the shelves inside will fold down from gravity alone. If you have more friction in the hinges, manually fold the shelves flat. Then fold the walls inside. The folded tower fits snugly inside the tray part.

To unfold the tower just open up the side walls and the shelves should fall to the correct position by gravity alone. If they don't unfold properly, fold them down using a finger. The top and middle shelf can be handled from the top, for the bottom shelf grab the hook from the bottom of the tower with a finger and pull it down.

Remixes

Feel free to remix this model as you wish. I added the CAD file so you can open and edit it in FreeCAD.
