Could someone with a Phoenix Home model let me know the dimensions?

Minis market is having a foam sale, and I need to decide which depth I need. Would 1.5" be deep enough?

The model itself is about 1.25" tall, 2.5" wide, and 3.25" long. On the base it is about 3.25" tall.

Yes. even with the Key extender underneath, its under 3cm in height, if you want it to sit on its belly

Great! That definitely sounds like the 1.5" foam would be right for the model. Thanks!
