This is an Adapter I made as a necessity to help hold 10Kg filament rolls on The Big Rep 1 printer we have. I just added 2 3/8" sheet metal screws to anchor the roll to the adapter.
Update: I made a revised longer version to better handle the weight of full 10kg spools. Print this at 60% infill or more for best results.
