That would put the wall thickness somewhere round 1.5mm. There's probably
scope for reducing the volume, say by giving it a golfball texture or even
just reducing the thickness of the flat part. That bit doesn't really need to
be stiff or strong because it's well supported by the next layer down, and it
would make the part quite a lot cheaper.
