2020 extrusion Customisable length

super strong (even printed vertically) 2020 extrusion, 4 walls. not load tested but i feel will hold some serious weight. customisable length to suit your needs, i also am currently in the process of creating brackets for attaching together and extended beyond the printer limits. ensure you have good adhesion from you filament and bed, i use supertack bed, have had some issues with some filaments but other filaments work brilliantly.
