I've been printing a huge amount of mustaches using my Makerbot. I made a few modifications to the original two piece model by gianteye to be able to print it in different sizes easily.

The S size is a scaled down mustache (75 % of the original size I think) with both pieces merged into one single piece which fits nicely in the Makerbot platform.

The M size is the same size as the original by gianteye but I arranged the pieces to be able to print them both at once.

The L size is a enlarged version as big as the Makerbot platform allows. I also modified the distance between the two pieces that hold the mustache in the nose to put them closer.

Print the stl files for the size of your choice:

small size: Mustache-S.stl estimated print time: 10 min

medium size: Mustache-M.stl estimated print time: 20 min (not sure)

large size: Mustache-Left-L.stl and Mustache-Right-L.stl estimated print time: 17 min each.
