About this 3D model

Got some cheap Jet filament from Amazon. It doesn't fit stock or any spool holder I have seen. So I designed this one to work with all the spools I've, Makerbot, SainSmart and Jet. The CAD image is V2, which has R, L indicators are added. R, L correspond to R, L printer heads. Photos are of a previous version, prints with PLA. This thing was made with Tinkercad.
