It turned out perfect!
We were up really late working on it, but it was well worth it as Bowser is happily basking right now.

We used 3/4 inch PVC pipe, 4 90 degree elbows, 4 split 90's for the top (picture a cube without the bottom attached, also used egg crate with shelf liner for padding and more egg crate for the ramp with zip ties to secure it.
We might get some indoor/outdoor carpet to use instead of the shelf liner....not so sure if the liner can handle the heat.
The whole time we were at Lowe's we couldn't find the egg crate, asked multiple people including a manager and they said they didn't carry it. We were going to go with plexiglass and just as they were cutting it the manager found us and said he found something that might work for us....he led us to the egg crate! LOL! And it was labeled "white egg crate"
Photos coming soon...
