Windsock mooring and spinner

thingiverse

Printed yet unmounted, I'm still waiting for a windsock to arrive, once it does I'll post the usual action shots. This simple windsock spinner and mooring post is based on the widely used 608-Z skateboard bearing. I designed this to go on our sailing club's flagpole; it features some spikes on top to deter birds and a deep skirt for weatherproofing. Print without support, but with a brim (unless you have super bed adhesion); print as orientated in the .stl files for strength in the post/bearing assembly. The bearing is fixed to the post using a self-tap screw in the tapered hole at the post end. Once secure, grease the bearing and then heat the cap in hot water to soften the internal fins. Shake dry and push the bearing into the cap. Once cooled, it should be strong and snug (if not, add some glue, but make sure it avoids the bearing internals). I painted the cap to seal it against the weather and help the bearing survive.
