Huge Parametric D20 die (.scad included)

If you want to :

• print a huge D20, beyond your printer's bed size
• dont want to waste your filament in infill
• have perfect D20 faces
• (optionally) make a d20 lamp like the one on cover

You've come to the right place !

You can print the D20 faces up to the maximum size of your bed, which will allow you to have a die whose size exceeds the size capabilities of your printer.

Select your face (number 1 to 20, or choose some original ones), put the numbered face on your printer, and your are done.
Once printing is complete, glue the faces together (undeceptors are here by design to help you position the parts correctly).

Note : the angles are very accurate, but even the slightest elephant's foot default on the print can degrade the final result, please pay attention to this point.

The provided STLs are done with these parameters (units are mm) :

• face_edge_outer_size=50;
• face_thickness=5;
• text_depth=1;
• tolerance=0.1;

The main parameter is face_edge_outer_size, which corresponds to the size of the aretes of the die.
When your render a face in OpenSCAD, the log will give you the total hight of the die, like this for “face_edge_outer_size=50” :

ECHO: TOTAL_ICOSAHEDRON_HEIGHT = 75.5761

To create a D20 lamp like mine

• Open the .scad file with openscad
• Set variable face_edge_outer_size to make a big dice (the one on the picture is for face_edge_outer_size=100 and face_thickness=5)
• Set variables for text_depth > face_thickness 
• Select a suitable font for the numbers (like the ones for making spray paint masks)
• Generate/export your faces in STL and print them
• Cover the inner faces in aluminium foil for maximum reflexion
• Fill the numbers with some transparent silicone
• Glue all faces together, except one (make the half of the dice, the other half and eventually glue the two part together)
• put a led strip inside the dice (i have ordered one with the electronic card and remote to be able to change colors and pattern), i have glued the electronic card on the inner side of the “6” so the plug fits in the dot. The led strip is just stuffed inside the dice without anything to hold it.

I have glued some metal and magnets to be able to remove the “6” face if i want to.

This is a lot of work, filling numbers with silicon is dirty and complicated, so expect to spend some time on the project !
