Everyone is a 3D printer, remix

This is a remix of the original project made by Joey_3D: https://www.thingiverse.com/thing:3602721

It's dimensions are 110x60x1mm.

I printed mine following these instructions:

1) I set in the slicer software (Cura 3.6) the skirt distance to about 25/30 mm

2) Using raft or brim is not recommended

3) I printed first the file "black.stl". Once the print ended I gently removed the black skirt (pay attention to not move the bed!), changed the filament and then I printed the "red.stl" file. In the same way I removed the red skirt, changed the filament and printed the "white.stl" file.
