5KG Filament Spool

I needed a stable 5KG Spool holder that could double up as a 3X 1KG spool holder and required no bearings.

BOM:

6x 210mm 30x30 Aluminium Extrusion
1x 250mm 30x30 Aluminium Extrusion
4x Angle Connectors
8x M5 Bolts
8x Aluminium nut inserts
1x 300mm - 12mm Diameter Stainlesss Steel Rod

I've included the Sketchup File for easy modification.
