This is a remix of the thing by pnoreck (thank you for making the original!) which consisted of an inlay that fits into another box with knurled lid. To reduce size I made a friction fit lid so that the inlay becomes the container itself rather than needing to be inserted into a larger box and lid. I would prefer to add threads to the container and make a matching lid, rather than the friction fit lid, but I don't yet know how to do that.
I made some changes so the items can be more easily lifted out and I repurposed the rectangular holes and added an extra one - these are now ND filter and wide angle lens holders and the filters protrude enough to allow me to lift them out with fingernails easily.
I moved the SD card adapter to underneath the wifi module and moved the wifi module down flush with the top. There's now a slot under the pan/tilt wheel for a spare micro SD card. I will line the friction fit lid with thin foam and that foam will rest on the controller wheel and ND filters/lenses, keeping them from rattling when the lid is on.
On my Monoprice Voxel (aka Adventurer 3) I print this at 101% scale, otherwise it's too small. Your printer may work at 100%.
Infill: Container: 15% Lid: 40%
Thank you to pnoreck for making the original and giving me the fusion file to work on. It's the best solution to store the osmo pocket accessories that I could wish for.
