Mavic 2 Sunshade Support
Description
This is my prototype for a sunshade that fits the Mavic 2 (Pro or Zoom) drone controller from DJI. I have looked at dozens of commercial sunshades, as well as all the sunshade designs here on Thingiverse, and they all have significant shortcomings. Some don't do a very good job of providing shade and, in fact, many of them only have walls on the side, without any hood over the top. Others do a good job of shading the smartphone and controller screens, but make it very difficult to get to all the buttons on the controller, or to easily access the touchscreen on the smartphone. I wanted a sunshade that would let me operate the controller and smartphone just like I do without the sunshade. I also wanted to still be able to use the range extenders that fit over the two antennas. I found a part that was designed to fit into the controller handle. Its original purpose was to provide an attachment point for a lanyard. I printed it and was impressed that it fit well and was strong enough to support the controller from a lanyard strap. So, I took that idea and made the part much longer so that the pole which supports the shade would be completely out of the way of my right hand. You can see from the cardboard prototype that the design achieves all of my goals, and having just flown the drone in full sun, it does a perfect job of eliminating all glare. I have labeled this a "work in progress" because at this point the only thing printed is the key part that provides the support. For the moment I am using a 5/16" wooden dowel for the support, and I have the back supported with a cardboard tab that is attached to velcro that is taped between the antennas (I have not yet removed the protective tape from that area, so I'll be able to remove the velcro without leaving any residue, when I come up with a better idea of how to clip the back of the shade. If there is interest, I'll publish a diagram of how to cut and fold the cardboard shade. I'm going to use this prototype for a few weeks, and then take a next step. The obvious next step is to replace the wooden dowel with a 3D printed part that will have a "skirt" where it fits into the support on one end, and into the shade on the other. That will eliminate the slight wobble one gets without that additional horizontal area at the junction point. I might print the box, although I'm not sure it will provide much of a functional advantage over the cardboard. Finally, I don't like the Velcro, and while it keeps the back from moving up or down, the shade still wobbles a bit. This doesn't interfere with its function, but it offends my design sensibility.
