Looking to build a 3 tub rack for three adult ball pythons

[tttaylorrr]

Do you have some pictures or something? i'm having a hard time seeing how you'd use one strip for three tubs??? Thanks for all your help! Is PVC similar price to melamine? i still have some melamine left over from the 6 foot tank i made for my retic.

PVC is much more expensive, but a lighter material (which is why i'm thinking of going PVC over melamine).

i can post photos/video of my rack's heat tape when i'm home. basically there's a hole cut out on the edge of each self so the heat tape can be fed through to the shelves below. my heat tape is weaved in an "S" shape through my three shelves.
