I include my design for your perusal. Let me know if you want a step by step. It'll take me some time but I'm in the process of collecting the pics and putting the literature together. This enclosure started out as a shelving system that you can buy from places like home depot.
I wanted to build a light enclosure that was stack-able both vertically and horizontally, kept temps well, was relatively inexpensive, looked good, and unlike most bearded dragon cages, could be knocked down for transport! I went for a form follows function design, and Ikea-like looks.
Though 5/8 or 3/4 melamine is a great insulator and keeps good temps with relatively low wattage, it tends to sag over time (depending on humidity) and is very heavy.
For this build I decided to go for cheap and light weight ¼ MDF, kept together by the steel frame of the shelving system I used. Materials cost me around $200 (including the shelves) for this 2 cage setup which is about the same for 2 all melamine cages using plexiglass doors (plexiglass is more expensive than glassbut keeps the heat in way better).
And as you can see, I have ample space to spare for my tarantulas, a Boa or two, or for more storage. You can actually build 3 cages from this shelving system if one were so inclined.
This is with the MDF panels, inset plexiglass doors, lights, and fake rocks installed. Note that the perforated steel frame serves as ventilation for each enclosure. This allows the units to be stacked on top, or beside each other. I use a single 50 watt bulb in the middle of each cage to achieve from 107 – 112 F basking, and 75 – 85 F cool side. If I placed the basking area more to one side I’ll get a much lower cool side around 70 F, so I opted to put it in the center.
Note that the Top enclosure will be slightly warmer than the bottom (hot air rises) so a lower wattage bulb or a dimmer may be used.
All MDF panels (Sides and Back) are held together with nuts and bolts.
T8 UVB tubes are still awaiting reflectors from Arcadia but are installed here using Euro style End cap connectors and clips. Both Tubes are powered by a single ballast that is screwed on to the top shelf the structure.
All joints have been caulked with white silicon and the fake rocks are made by yours truly as well. The ceiling is covered with an aluminized Mylar tape for better insulation and heat reflection. All exposed steel within the cage is treated with a carboard/ Aluminized Mylar covering to prevent heat from dissipating to the frame. Flooring is linoleum (fake bathroom tile) , and the rosewood finish is contact paper.
If you guys are interested I can post the entire build step by step. Let me know.
