This is a Rugged Box by @Whity remixed to fit DJI FPV Controller 3 + added optional DJI logo.

I printed it in Gray, White and Black PETG at 0.2 layer height with 0.4 nozzle using Centauri Carbon.
Used Red TPU for the seal.
The files are no MCU friendly - I do not own one (come on Elegoo).

What do you need to assemble the box:

Non 3d printed stuff:
- (Optional) Glue if you want the logo on the lid, I recommend cyanoacryllic
- (Optional) 6x M3x34mm bolts with nuts if you do not want to use the 3d printed pins

What do you need to print:

- 1x The lid (either DJIboxLidNoLogo.3mf if you do not want the logo, or DJIboxLidWithLogo.3mf if you want the DJI logo)
- (Optional) 1x The logo for the lid (DJIbox.LidLogo.3mf) if you picked the lid with the logo
- 1x The bottom half of the box (DJIboxBottom.3mf)
- 2x The latch (DJIboxLatch.3mf)
- (Optional) 6x The hinge/latch pins (DJIboxHingePin.3mf) if you don't want to use the M3 bolts
- (Recommended) 1x The TPU seal (DJIboxTPUseal.3mf). You don't need it, but it gives the well needed springiness and tension to the latches

You can glue some kind of foam or fabric to the inside of the box to make the controller a bit more snug and secure.
