Here is a small collection of (wall)pulleys:

You need one of every following item:

1. "rh2 rolle.stl"
2. "rh2 shaft.stl"
3. 685 bearing, I used these 3D Printable bearings

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)

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

3. "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

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