pulley collection

Here is a small collection of (wall)pulleys:

**You need one of every following item:**

1. "rh2 rolle.stl"
1. "rh2 shaft.stl"
1. 685 bearing, I used these 3D Printable [bearings](https://www.thingiverse.com/thing:4851975)

**And one of the main pully-things:**

1. "rh2 90": pulley for about 10° to I guess 360° (in my usecase i used them a3 90° ones thats why the name)

1. "rh2 s90": pulley for about 10 to 360° but side with screwholes on the side

1. "rh2 270": pulley for about 270° or -90° (in my case for going around corners) this one has a secured tunnel that protects the cord from slipping Note: tight tolerances at the tunnel

1. "rh2 270b": pulley for about 270° or -90° (again) secured tunnel that protects the cord from slipping BUT more lose for bigger cords
