XYZ Filament spool

Apologies for the phallic shape...but it at least works. I,m not intending on making this any nicer, it does the job. I made this to fit a larger filament spool to the Davinci XYZ Junior. There's loads online for the other printers, but I couldn't find one for mine. It can be fitted directly to the rails with an M4 nut, bolt and washer, I've just cable tied mine on and works fine. I have other files for a filament guide.
