For those 4x10 format film shooters out there here is a drying frame for after you develop those 4x10 sheets of film.

I have incorporated 6 holes for use with 2M heat inserts, but if you would rather the whole thing can be glued with cyano glue. I am doing a combo of screws and glue.

I would suggest PETG as the material to create this with due to is chemical resistance and low water absorption.

I designed this after I built this 4x10 camera that Morton Kolve was kind enough to up on Thingiverse
