Lid Mod for Rob Bieber's 4x5 Wet Plate Holder

thingiverse

Very simple mod to the lid component of Robert Bieber's 4x5 Wet Plate Holder. Basically it's a 0.4mm slit in which you can squeeze in a 0.25 mm leaf spring. The width is 1cm but I found that a wide leaf spring at that thickness is too strong, and something like 5mm is better. The slit is tight enough that you won't need any treatment like bonding, but it may be a good idea to slip some epoxy in there and bonding it after you're satisfied with your spring selection and tension setting, if only to ensure strength of the lid at that site.
