Modified Slinky Seismometer

After working with the earlier Slinky Seismometer parts I'd made (http://www.thingiverse.com/thing:172657), I set out to make an easier to build model. These parts can be connected by 1/4 inch nylon threaded rods and held in place with nylon nuts. (You can't use metal rods, as the magnets in the middle will be attracted to metal rods, which will mess up the seismometer.)
