A 12-sided dice labelled with numbers from 1-12 normal font.
The numbers are printed separately on small plates (bicolour print with filament change recommended) and then glued to the dice itself with superglue.
If coloured filament with a good contrast is chosen, then visually impaired learners can read the numbers well.
Printed model of the author
This model was designed and tested as part of the 3D4VIP project.
Dice
The dice is printed in two parts and then glued together with superglue. This way a better print quality can be achieved. Infill is necessary for the dice. A value of 4-5% is sufficient, whereby more infill contributes to a more stable dice and better rolling behaviour.
It is sufficient to print the bottom with only 1-2 layers in order not to change the rolling behaviour of the dice too much. Without a closed bottom layer, it is difficult to glue the two halves together.
Labels
The plates are arranged flat on the print bed and can all be printed simultaneously. To get the plates to be bicolor at the end, it requires a color change for printers with only one printhead. Instructions for Cura can be found in the Guidelines in Article 5.
If you print the first layer with 0.3mm and then each further layer with 0.1mm, you have to set the color change for layer number 14.
Take care that the prints do not have an elephant foot!
