2020 spool holder

This spool holder is made for the Hypercube in particular, but could be used on any 2020 aluminium extrusion based frame. The idea for Hypercube is to have everything inside the frame, I am working on that as MK2 under my designs. I use 500mm vertical extrusions, with the spool underneath the heatbead, 200mm height remains. If I need more height, the spool holder will move to the front (no screw holes designed to be portable). The included 52mm adaptor is without tolerance on the 30mm spool pin, so you can use it to even hold the spool in place when used vertically..
