The Reverse bowden tube kit includes a panel mount spool holder, 24" of bowden tube, 2 press fit tube fittings, and a frame mount that is compatible with the prusa i3. This is an easy to setup kit that requires that you'll need to drill one hole to mount your filament holder to the side panel of your enclosure. This kit should be able to adapt most any enclosure (even your own DIY) as long as the spool holder can be mounted on the left or right side wall.
