The file 'Improved R2-D2 Minifig Legs 3D Printer Model' is (stl) file type, size is 39.6KB.
the original legs of the Lego Minifig for R2 look kinda un-R2-y... so heres a proposed fix :-)
these technic pins are used:
for the "shoulder": http://www.brickowl.com/catalog/lego-three-quarter-pin-32002
for the "ankle": http://www.brickowl.com/catalog/lego-half-pin-with-stud-4274
and for the front "foot": http://www.brickowl.com/catalog/lego-axle-2-with-grooves-32062
R2 can be made to stand up (the front foot is designed to sit in two angles/positions on a plate) - but for that the rear feet have to be put on the outside of the legs
