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.

Example prompt
Design an ND filter case for a DJI Mini 4 Pro with six slots 26 x 9 x 20 mm and 0.5 mm clearance, a 1 mm pad rib under each slot, engraved labels ND8 to ND256 above the slots, a sliding lid on 1 mm rails with a detent bump, a 4 mm lanyard hole and 1.5 mm walls.
Fit notes
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, add Osmo Pocket 3 slots in the chat and download the STL.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
