About this 3D model

"update" the V2 file has a taper to make it sturdier, I also added the CAD files. I designed this 57mm adapter to fit my Prusa I3 Holder, It works well, snaps into the spool securely and turn very smoothly while printing. The inside diameter is meant for the 16mm Prusa original holder but can be used on others.
