I designed this bowl to fit into a corner of my gecko's terrerium. The bowl needed to fit in the available space and contain sufficient volume for water to provide humidity.
I can easily redesign this model to the specific dimension you require, because I designed it with openSCAD. The wide range of possible dimensions mean that making a Co-Creator template would generally be more costly, as the price would be set at the maxiumum.
My 3D design work focuses on modeling fossil creatures which have generally otherwise been ignored. You won't find dinosaurs here, but you might find obscure molluscs or interesting invertebrates.
I will have some random other models available if I think someone might find them useful.
