Parrot Disco Lens Protector Mk 4

This design stands out as the most impressive so far. The inner ring is securely attached to the nose cowl using double-sided tape or a strong adhesive. The lens is carefully positioned on top, and the outer ring is gently pushed into place. For added stability, electrician's tape can be used to secure it in position. To achieve an authentic look, paint the inner ring in the conical area with a matte black finish, while also coating the innermost section of the nose cowl with a matching color. Ensure that the nose cowl is positioned as far back on the fuselage as possible to avoid any visibility issues. On my plane, I encountered a similar problem where the top lid was slightly too long, causing the nose cowl to shift forward and sometimes appear in the videos. To resolve this, I had to trim the top lid. To create an accurate template, carefully scribe the outline onto the 1 mm Lexan backing paper and cut closely. This will allow the lens to fit seamlessly without any need for sanding. It's essential to use a thinner sheet of Lexan (1 mm) to avoid any visibility issues with the outer ring in the camera view. In the STL files, the inner ring's outer diameter is identical to the outer ring's inner diameter. On my printer, I found that scaling down the inner ring by 1% resulted in a snug fit. You should experiment and find the optimal setting for your specific equipment. Watch this video for more insights: https://www.youtube.com/watch?v=yOFLpJ_cMT8
