Pulley Remover

This is a simple and easy to print pulley remover / puller. It can be used to remove pulley from motor shaft or to remove bicycle chain-rings to name a few cases.

- Bolt spec is M16, if you already have one you might not need to print puller-bolt.stl
- I provided a an adaptor for a 8mm motor shaft and an "Arrow head" adaptor as well.

### Printing Instructions

- Prints are already oriented in the optimal position
- None of the parts require supports
- increase number of wall (4+), top layersand bottom layers to add strength to the part
- Print puller-arms.stl with 100% infill
- puller-bolt.stl is a slightly longer print compared to the other 3 parts.
- puller-bolt.stl might be good to print with a brim

### Weaknesses/Future Improvements
- The weak point is the hinge
- A version with 3 arms and with 4 arms would be good

### Updates

- Added a version with 4 arms
