Bearing pulley

So, i had to replace the 40 yo. pulley from the top of the mast of my boat and i decided to print one. I decided to make a bearing pulley so it would run smoother.

It has very tight tolerances so you have to break the gears free with a little bit of bending after printing!!!!!!  It seems solid at first but will break free after a little bit of bending. The tolerances are really tight so the parts will not have a lot of play!

Also you need to import both parts at the same time inside the slicer. 

The diameter of the groove for the cable/wire is 4mm!

Print settings: 

Filament: XT-CF20

0.2mm layer height 

Temp: Bed 90°C, Hotend 260°C (i used glue stick on the bed) 

Max print volume: 8mm³/s

Fan speed: between 20%-50%

Support: yes, I printed it with the tree support funciton of my X1 Carbon and the overhangs look good and everything came off pretty well.
