COASTERS:

Engine Piston

Brake Rotor: Can also be used as the base for the Piston Assembly below

**** PISTON AND CONNECTING ROD****

Minimal assembly required 

Make sure to check the polarity of magnets when assembling 

I made a Piston and connecting rod assembly that mounts to a gear base/brake rotor. They are held together by four 6 X 3mm magnets, which I have linked below. The holes for the magnets are slightly oversized so I would add a small amount of super glue to keep them in place. The assembly can hold the weight of a full soda can, but it may knock over because it is top-heavy, so I recommend using it as a snack container instead. I plan to revise the model to make printing easier and reduce the support material used. 

It would be greatly appreciated if you drop a like and share this design with your friends. Thanks!!
