Tinkeriffic BB Bearing 40mm Spool Spindle Jim Rodda

Nothing fancy here, just a remix of of my 32mm Tinkeriffic BB Bearing spindle. This one fits snugly in a **40mm** spool.

This three-part solution (thirteen parts, if one counts the 4.5mm BB's (http://bit.ly/1ngex61) is designed to use a Tinkertoy rod as an axle and is a much, much smoother ride for your filament spools.

I found inserting BB's into the original 608 bearing to be frustrating so I split the bearing in two and left it to the end user to super glue the parts together.
