this is an awesome print I made with hueforge. The only trouble is, you must change the filament 4 times during the print….

here are the directions

Project: hex.hfp
Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

The Model is 200x200mm in size
You may print at higher layer heights below the Base Thickness of 0.48mm
The Max allowed Thickness is 2.24mm and the Actual Thickness is 2.24mm

#e2dedb PLA PolyLite White  Transmission Distance: 5
This print uses 4 unique filaments

Swap Instructions:
Start with Black
At layer #9 (0.8mm) swap to Blue Gray
At layer #12 (1.04mm) swap to Grey
At layer #17 (1.44mm) swap to White for the rest.
the origional is in colour and the black and white result is black and white but the blend of colours does the job…

I have licensed this in the public domain but I downloaded the image from the internet, so selling this model might be illegal…
