Windmill mk4

Okay, so I've uploaded something like this before. However each time I've had to replace the windmill due to ageing of the ABS plastic I use I tend to make a slight change.

This is the model that I've put up this summer.

Compared with the previous version (https://www.thingiverse.com/thing:451363) it's mounting is more flexible both how you can mount it, how much variation is possible with vertical placement of the windmill and also because it can flex a bit more then the previous plastic stand.

For this version one needs to buy:

* M8 theaded rod, stainless for endless reusability, zinc plated might start to corrode in a while.
* one M8 nut
* one M8 bolt hex head, If I recall correctly about 80 or 100 mm long.
* One M8 round coupler nut (I used 2 because my bolt was slightly to long)
* One cleaned out 608 bearing.
* 4 sunken head Screws

I clean out the grease from the bearing and remove the dustcaps from the bearing. As long as it moves it won't rust out to much. Cl
