Bàn xoay Prusament Turn Table

This is a turn table using the iconic ends of the Prusament spools and some spare bottom bracket bearings I had on hand. The bearing type is 6806, 30 x 42 x 7mm

The assembled table is just under 30mm high and I have included in the design an optional bearing keeper to stiffen the assembly. 

Required to build:
1 x Base
1 x Prusament Holder
1 x 6806 bearing

Optional:
1 x Bearing Keeper Bottom

1 x Bearing Keeper Top

1 x M3 screw (between 5-10mm long)
