To fit Footy, Micro Magic, RG65/DF65 class RC sailboats.

Works fine even without ball bearing (They may get rusty and just make trouble anyway).

The diameter of the pulley is around 8mm, a bit bigger than the original DF or MM pulleys, but that size did not worked for me if I tried to print.

The pulley block is designed to accomodate M2 threaded screw to fix to the servo arm but can still rotate freely (assuming it's not overtighten).

The pulley block is included in a single shot version (requires support which is not easy to remove), and a two part version (requires a bit of superglue, but may print nicer).

For the pullex axle I used a piece of metal rod from the “bead store” which is made out of some kind of copper, the proper size of stainless steel or hard aluminium rod may be better.

Printed from eSun PLA+ for good abrasion resistance and strength. 

 

Bon voyage!
