Thank you for the replies everyone! I do think I'm leaning towards building one myself, especially since it doesn't look worth it price wise to purchase smaller racks (larger racks I would defiantly want to purchase though!) I do like building thinks, but so far most of the stuff I've constructed have been impractical, like models of DaVincis flying machines, sculptures, stuff like that. I may not have practical experience building useful things, but I am a little familiar with most of the basic tools at least! XD

Is melamine the best material to start with? I know it's easy for me to get, and have pre cut, so I do like that idea. Luckily there is a reptile store close to my work where I know I can pick up heat tape, and a temp gun/thermostat/ect if the price is right. Any precautions I should take with attaching the heat tape to the rack?

As well, I know I've seen it around here, but what size of tub is the best for Ball pythons?
