Bay 1 Rolleipol Thickness

Good day folks,

I'm in the process of designing a wooden storage case for my Rolleiflex Automat's lens accessories (Filter, Hood, etc...) as my original leather case is falling to pieces. I don't currently own a Rolleipol filter but do plan on acquiring one in the near future and want to include a slot for it in the box.

Would any of you happen to own a Bay 1 Rolleipol and be able to give me an idea of how thick (or tall) the filter is? I already imagine the diameter is the same as the other Rollei Bay 1 filters at roughly 37mm (1.5" ish).

Thank you for any assistance.

37.5mm diameter.
10.8mm thick .

Or

1.47" diameter .
0.43" thick .
Sorry my gauge doesn't do fractions of an inch , just decimal points . Call it 1 1/2" X 1/2" .

Regards , Neil .

That's just fantastic, thank you very much for your time.
