Minty has the platform on the PS at 7.5 x 17mm.

I measured my platform on the V4 at 14.5mm x 9mm which is 130.5mm². Hence I said slightly larger on the V4.
The part of the lid with the posts is a removable insert only held in by an o-ring so you could run it without that and have an absolutely huge mesh. But you'd be sacrificing airflow control by doing that.
I've removed the o-ring from insert anyway so it doesn't stick in the lid. This way I can remove and attach the insert and lid separately so I can be sure that I'm not hitting the edges of the mesh as I do. Here's how it looks with just the insert.
