Filament spool holder (REAL filament)

I use the REAL filament 1KG spools and they come with transparent spools. I created custom made spool support so you can place the spools on a rod. The inside diameter is 18mm.

Print them as fast and as ugly you can. They are only needed to make your spool to roll nice on your spool holder.

The design is slim fit. I print them on a bigger scale like 1.02 and lay them in the freezer for 5 mins. Remove them from the freezer and push them in the spooler for a tight fit.
