Customizable Filament Rod

This is a height-customizable spool rod that is compatible with the Flashforge Dreamer's standard spool holder. It is also compatible with @BaronWilliam's Top Mount and Internal Side Mount Omnistands. I designed this to be used with my Universal Spool Hub. If you are using this rod inside the Dreamer, the max height (aka length) of the rod should be 90 mm. If you are using this outside the printer, then I would suggest a max of 125 mm. The axle diameter is 19 mm.
