Making my own incubator/hatchling tub

[Horness]

I'm thinking of making my own incubator/hatchling setup for my Leo's out of a Faunarium and some tuppaware containers I have.

The setup includes the following :

46x30x17cm Faunarium

This would be lined with paper towel, and inside have the usual hides, plus small jam jar lids for water, mealies and calcium.

39x15cm Heat Strip

This would be under the faunarium, not inside, and connected to a a Habistat mat thermostat. Could change this for a 20x20cm mat, as I'd have to buy this.

Within this I would put a small tuppaware container with vermiculite inside, plus the eggs. I have a couple of digital thermometers I can attach to the lids of both containers, and can move the "incubator" around within the faunarium to get the right temperature over or around the mat underneath.
Once ("if") the eggs hatch, I can move the hatchlings out of the home made incubator and in to the main part of the faunarium.

Thoughts, suggestions etc. all appreciated before I put this in to action.

Cheers
