The file 'Universal Spool Clip Filament (1.75 Mm) 3D Printer Model' is (stl) file type, size is 381.1KB.
This is a similar project then this one (not mine): http://www.thingiverse.com/thing:282242
But this mine version is fastest to apply to the spool respect the other.
U can print 20 pieces together too.
