The file 'Prusa I3 Steel Spool Holder 3D Printer Model' is (stp,stl) file type, size is 7.4MB.
Printed frame to hold a filament spool for a Prusa i3 Steel. stp file has all fasteners and bearings. uses 4 - 608zz bearings
EDIT
I changed a few small parts in the model. all new STL files are uploaded as well as new step file. printed and tested. works very well.
