Load Bearing style Filament Reel Holder

My filament sits flat on the top of my PC, but the printer kept pulling it off. This was an attempt at a holder to solve this. Bearings are standard 6mm BB pellets.
In reality the reel slides on the top part, making the bearing bit useless... But as POC it works.

120mm diameter to fit on Huxley's bed, 50mm tapered cylinder to suit 3DFilaPrint spools.

Modelled in Solidworks, Printed in Black PLA at 0.15mm on Reprappro Huxley
