AIO Filament Spool Adapter

I have a Monoprice Voxel printer that takes a 0.5kg spool. The spool holder built into the printer is a much smaller rod than my AIO spools, so this adapter was needed. The Monoprice brand filament the printer came with had a small inner spindle radius, but the AIO spools are much larger. This may work for other printers but I'm not sure.
