Large Filament Spool Holder

I recently received a new roll of filament that had a larger diameter center hole that every other roll I have ever had. Designed this to work with the larger bore as well as standard size rolls. Tried to minimize filament usage and at the same time make it look kinda cool :-)

Made for 8mm rod that comes with a number of 3D printers.

I made mine with 15% infill. No supports needed.

edit: Change height so that they would not contact one another when used on large diameter bores.
