Simple top mounted filament reel holder for Kossel mini

Top mounted filament reel stands for a mini kossel delta type printer.
Requires a 6mm rod (I used some carbon fibre rod that same stuff as is used for the diagonal rods on a lot of mini kossel designs, you could use anything that'll fit).
Should fit just about any 1kg reel. I have quite a variety now, of varying widths and internal and external diameters, and they all fit fine.
