NOTE: Files must be split to reveal the numbers.
These are a multi material version of numbered miniature base markers I made to use with printed miniatures for the board game Gloomhaven. I printed them in white to represent the standard monsters. An elite marker, printed in yellow, can be snapped into the base to indicate an elite monster.
These files are for printers that can print 2 or more colors at once. STLs must be split to reveal the numbers. If you are using slic3r this can be done by double clicking on the object, selecting the object name in the pop-up window and pressing split. Different extruders can then be assigned to the base and the numbers. You can also try using the .3MF files attached that have the models pre-split and grouped in sets of 6 and 10.
