A companion cube from the video game Portal. Designed by Andrew Lindsey and available on Thingiverse here: https://www.thingiverse.com/thing:173570
I printed this as a cake topper for my Son's birthday cake.
See the above Thingiverse link for more information.
I have sliced the objects into three files, one for white, one for pink and one for grey, I have enabled brims because the individual parts are reasonably small.
The grey parts use the Prusa PLA filament profile, while the white and pink parts use the Generic PLA filament profile.
I didn't have pink filament, so I printed them white and painted them pink.
