Dual Colour Dice (foldable)

This design of a fair (all sides have equal probability to be rolled), utilizes two prints with different colours, stackt on each other. All sides of the dice are printed flat on the print-bed and then folded into the final dice.

Last Meters Competition

This dice uses two materials. One for the pips and one for the dice body. To print the pips only 2cm of 1.75mm filament are needed. The dice body itself uses 80cm of 1.75mm filament.

Printing Technique

First the pips are printed as a separate file in one colour. Without removing the pips from the print bed, the filament is changed to a new colour and the dice body is printed on top and around of the pips with a second print job. Finally, the finished print is folded to a working dice while clicking the sides satisfyingly into place.

Multiple Designs

This design comes in a normal and a heavy variant. The heavy variant fills out the dice body as much as possible to add just a little more weight for a better feel.

This dice is one of multiple similar foldable dice designs:

Tips and tricks

To Slice the pips in Prusa Slicer, you need to cut the part at 0.2mm and only keep the top part. This allows to print all numbers oriented correctly as one part. While slicing, make sure, that you do not move the loaded part. That ensures the correct orientation.

For the pips to print well, you need a good first layer calibration. I tend to print those by lowering the nozzle by 0.15mm compared to normal first layer z-height.

Make sure to remove the skirt after the pips are printed. If you have some stringing, try to clean up the most prominent whisps for a clean main print.

Make sure, that the print bed does not cool down between printing the pips and the dice body.

After printing, the satisfying folding of the dice is next. I found the best order to fold the dice is to start with folding the 6 and 1 onto the 4, then continue with 2 and 5 and finally close it all up by folding the 3.

If you get stretchmarks on the seams, you can use a lighter to restore the original colour. Let the flame touch the discoloured edge for a few split seconds until the white stretchmarks disappear.
