Frame reducer 8x10inch to 13x18cm

Nocing really fancy, I needed a frame reducer for my 8x10inch camera to get 13x18cm pictures.
So I designed it in Fusion 360 and here is the result. I'm making wetplates by the way, so I don't think this could fit for film unless you make some kind of a tray or something to hold the film flat.
I designed it in two parts that needs to be glued because my printer isn't big enough.
Printed nice in PETG with 15% infill and supports.
