Now this is just the run down of everything
I of course cut everything up, you can purchase everything you see here from your local
hardware store and plastic store for really cheap.

First step

Stack 2 of the expanded pvc pieces that are the same size and drill a whole in the center
and two holes each three quarters of an inch from the edge from the center line.

Now cut your aluminum rods to size and stick them through,
now you should have a comparable piece down below

Repeat for all Axis
