Stationary Dice

See it in action:

Features:

• Easily prints in multiple colors
• Can use multiple dice-face colors per “die”
• Use PrusaSlicer negative volume feature to create any style of dice faces
• Assembles without glue
• Rotates nicely without bearings, though common 608 bearings can be used.
• Uses common magnets to enable discreet stopping points
• All magnets pop out with a paper clip
• Dice can be grouped in any number of configurations
• Easily take dice off of assembly to use in different configurations
• Prints without supports
• Prints at 0.3mm layer height on a 4mm nozzle

Magnets needed:

• Each “die” uses 6  magnets that are 3mm in diameter with a height of 1.6 mm, though the height can be less
• Each support uses one 3/16-inch-diameter by 1/16-inch-height magnet for attraction to the neighboring “die”. A second 3mm x 1.6mm magnet can be used to repel the neighboring “die”. The repelling magnet reduces (though does not eliminate) the possibility of the die stopping halfway between the attracting magnets.

Instructions:

• No supports needed for any models.
• I print at 0.3mm layer height except for the nut and bolt. I print those at 0.2mm.
• All pieces can snap together. No glue needed. A small hammer may be needed to fully seat the magnets
• Magnets can be popped out with a paper clip inserted from the other side.
• Some rubber feet on the bottom of the base help prevent slipping on smooth surfaces.
• Face the supports so that the magnets on the support do not touch the magnets on the dice. (See photos)
