Speedybee Bee25 DJI O4 Pro Mount

Bee25 mount for the DJI O4 Air Unit Pro

I created two versions, v1 has “Zip Tie” antenna mounts - was trying to make a friction fit for the antenna but still requires a zip tie. Use this model if you don't want to take the o4's bottom plate off. V2 has 45 degree angled antenna mounts - this will require you to remove the bottom plate so you can remove the antennas and feed them through the mounts - be careful there is a ribbon cable attached to the bottom plate and the main board.

Hardware Required                                                                                                                                 11 m2x8 mm screws

• 4 for the mounts to the Bee25 
• 4 for the camera mounts (you may need washers on the top angle adjustment; came out larger on my printer)
• 3 for the air unit mounts 

1 m2x16 mm and nut to secure the two halves together at the back

All the hardware is in this screw kit: https://www.amazon.com/gp/product/B09TVP1G5B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

I mounted mine with the connection cable at the back - antennas at the front near the camera. This will expose the micro-sd card/bind button at the top, USB port at the bottom. You can tuck the camera cable and antennas between the two halves, any excess camera cable tucks neatly behind the camera.

I had to widen the v2 antenna mounts a bit with a drill bit - I had set it to 3.5 mm wide which should fit the antenna and connector but I had trouble feeding the antenna through - could be the TPU I used.

I highly recommend printing in TPU, upside down to reduce the amount of overhangs. TPU only for strength and vibration dampening - not getting any jello or vibrations at least flying inside (throttle is scaled). I printed mine at 15 mm/s, .1 mm layer height and each half took about 5 hours on a Kobra 2 printer.

There's only 1 half, you can mirror the model in your slicer - worked perfectly and only needed to design one half. I'd print one at a time - screenshots are just for illustration purposes.

No overheating issues even flying inside - the front shelf above the camera acts as an air intake and left plenty of the air unit exposed for cooling purposes.
