Hogwarts house crests turned into keychains. All keychains were printed with multiple layer color swaps, but can be printed without any color swaps. The color swaps are saved in the .3mf file, but if you are completing manual layer changes, the swaps are at the following layer heights when printing .2mm height:
Gryffindor: Layers 10, 17, 23, 26 (gold, red, gold, red, gold)
Slytherin: Layers 17, 23, 31 (green, grey, green, grey)
Ravenclaw: Layers 16, 29 (grey, blue, grey)
Hufflepuff: Layers 9, 17, 20, 23 (yellow, black, yellow, black, yellow)
The author remixed this model.
Slimmed down and added keyrings to the top left corner of all crests.
