About this 3D model

After hearing a lot of talk about reverse bowden and how it improves the quality of you prints, I decided to design an upgrade for my Mk2S Prusa i3. I wante the update to be as orginal to the stock i3 as I could. So I modified the original parts to accept Bowden couplers and then extended the Z stop in order to be able to feed filament from a desktop mounted spool.
