Buying the supplies for your branch will require a trip to the local big box stores or even your local hardware store, but if you have different kinds of reptiles, you most likely may have some of this stuff already, plus scrap PVC pipe can be gotten from plumber friends and the infrared stripper lamp borrowed from painter friends. The benefit is that once the supplies are in hand, you are now equipped to make several branches for any size habitat.
The branch I made was for my small-ish stunted iguana, who does not have very good use of his back legs. The branch needed to be big enough for a comfortable basking branch and allow a good grip since he is a weak climber.
A word of caution about bending the PVC pipe. The use of a heat lamp, such as is used to strip paint, is desired over the open flame of an acetylene torch. A hand torch will work but be aware that burning PVC fumes can, well, kill you— so use the heat lamp and obey all safety precautions.
