Flik Wing DJI O4 Pro Air Unit Mount & Lens/ND Protector

The O4 Lens/ND Protector should be printed in TPU face down with supports enabled. 
Once printed, I centered the camera mount on the nose and traced out the 22mm(W) x 25mm(H) opening and cut it out. I then traced out the full width(34mm) of the mount on left and right side of the nose and then trimmed these small pieces so that whole camera mount can sit slightly recessed. After test fitting it with the camera installed, I slid the mount ¾ of the way out and applied E6000 around all sides before reseating it in place. I verified it was rotated correctly and square before placing the wing on its nose and applying bean bags to the prop/motor to weight it down. This way the camera mount can be fully seated and held in place until the E6000 sets up. The option to install the screws is up to you and your creativity but I personally choose to leave them out. 

The Air Unit mount should be printed in ABS or PLA and the scoops should be printed in TPU but could also be printed in ABS or PLA. The scoops print best with the thin vent opening faced down on the build plate.

I marked out the openings and left a 2-3mm lip in the foam all the way around the openings before using E6000 to glue the vents in place. I then used fabric sewing pins to pin the vents in place while the glue sets up, similar to the Flik Wing build instructions. Once the glue sets, I then trimmed the foam on the inside of the lid for smoother air flow through the frame.

The air unit mount can be pushed into the foam slightly on one side before bending the mount and foam slightly to get the other side pushed in. I found you can use a small screwdriver to pre-puncture these holes in the foam to make it easier get the mount installed. Gluing the mount in is optional but check your CG before doing so. You'll need 2 to 4 M2 screws for mounting the air unit to the mount. The shorter mount arms will face the rear while the longer 2 will be towards the front. 

The front skid is my newest design to add a little protection to the belly of the Flik since removing the traditional old fashioned skids that I used on both the front and rear. I designed this skid to be printed flat and then bent into place before being attached with E6000. I printed mine using NylonX and added/left a two perimeter brim to help with attaching. I then heated the skid up a bit to help with bending it inwards around the half way point in both directions to match the contour of the foam. After test fitting, I added E6000 and using a clamp to help hold it in place while the glue dries. I used a few small bean/sand bags to help spread the load while clamping the skid in place.
