4 slot filter wheel

I wanted a quick way to change filters on my cheapo telescope rig so I created a filter wheel.

It is inspired by what you can find commercially on the market. The only draw back is the load that it can support, I've only used it with a RPi camera and this was what is was designed for, it could work with a heavier camera but I'd be a little scared putting my DSLR on it.

The design is modular, I wanted the design to print without supports and the only way to do so was by creating it in 5 separate parts.

The magnets hold the position of the filters while rotating the wheel.

requires:
- 8 x 2x1mm round magnets
- 1 skateboard bearing
- 12 m3 x 6 mm screws
