2020 extrusion brackets

I made a light HALO/4 spool filament holder for my Zonestar Z8 printer. The original 4 roll filament holder that came with the printer was very poor quality and not very sturdy. These two brackets enable you to "T" 2020 extrusions together holding them firm from the top and bottom. They can be used for many other projects involving 2020 extrusions.
