So, how to make one? Go down to your local hardware store and buy some PVC, connectors, and some red hot blue glue. For the tripod connector, get a long 1/4" machine bolt and some washers and nuts that fit. PVC caps work really well, you just need to drill a couple holes. When using the PVC glue, be sure to do it outside or somewhere where there's a lot of air (it gives off a lot of fumes, you'll see).
Good luck! If you have any questions, I'd be happy to answer them.http://www.takezer0.com/
