The file 'Adjustable Straight Leg Hanging Art Mobile 3D Printer Model' is (stl) file type, size is 195.6KB.
I took the fantastic super easy mobile, made it larger, adjusted everything to fit nice and tight, and added an improved key as well as a new scalloped straight leg spoke.
Included in the .stl is everything you need to make a mobile: 6 legs, one key, and two hubs.
