Absurd Toothbrush Holder

A friend asked me to make here a toothbrush holder that covered her toothbrush when she was not using it.  Rather than simply making two telescoping cylinders, I decided to make the most over complicated toothbrush holder in existence.  

This monstrosity uses a lever arm that turns some gears that move some racks that simultaneously lift a platform and swing open the lid.  I can confirm that it works as intended but the design could certainly be improved.  I have no intension of making another one of these or making improvements to the design so I've included the .sldprt files if anyone wants to give it a shot.  

The assembly process is challenging.  If you enjoy frustration this is the build for you.  Good luck, you'll need it.
