DJI Mini 4 Pro ND filter case with six slots
A pocket case for the snap-on ND filters used by the DJI Mini 4 Pro and Mini 3 Pro, which measure roughly 25 x 24 mm and 8 mm deep including the clip and are easy to lose in a bag. Six slots 26 x 9 mm and 20 mm deep hold ND8 through ND256 upright with 0.5 mm clearance and a labelled notch above each, and a 1 mm pad rib under each filter keeps the glass off the floor. The lid slides on 1 mm rails and closes with a detent bump, and a 4 mm lanyard hole clips the case to the drone bag. Print it upright with 1.5 mm walls; the lid prints flat.
DJI's filter sets change size every generation, and a case for Air 3 filters is too loose for the Mini. Tell SpeakCAD your filter dimensions and count, preview the case in the browser without paying, add Osmo Pocket 3 slots in the chat and download the STL.
