Not happy with all the missing parts on my Olympus, so I designed and printed them all.
Battery door cover - took me 6 iterations to get it to the perfect dimension, also the fact I was printing with an old 3D printer, designed to match the tolerance.
Eyecup - This is a bummer. I could have printed with soft TPU (I do not have the filament) to mimic the rubber deformation. Instead, this is just an aesthetic part with no deformation. Designed with bridging without support material.
Accessory port cover - My design skill has gotten better. I got the perfect fitting on the 2nd try!
