Marble Machine Clip

This is an alternate clip to hold the pieces of [Jazzmyn's Customizable Marble Machine](http://www.thingiverse.com/thing:892619) together. The clip has a block in the back of it designed to hold a cylindrical magnet. Using these clips with magnets inserted and the track pieces from Jazzmyn's Customizable Marble Machine you can build a marble track that mounts to a ferrous metal surface.

This clip is a much tighter fit on the track pieces than the original clips from Jazzmyn's set. They have a slightly larger lip around the edges and have slightly smaller interior diameter so they grip the track pieces more tightly. My intent was to make the clips grip the rings tightly enough that no zip ties are needed.

I designed this clip to be used with 1/4 inch x 1/4 inch neodymium magnets that I purchased from Applied Magnets. As of the time I write this, these are model #ND014 in the www.magnet4less.com store. You can find these magnets at [this link](http://www.magnet4less.com/product_inf
