Drone wall mount

I used the original as a template.

Increased the length of the studs and made them conical, so the drone can't slide off as easily and so it can support drones that have nuts under the base plate (such as an x220) with a bit more margin.

Also added a few diagonal arms for extra support because I noticed the arms tended to sag a little under the weight.

To be mounted with some double sided sticky tags.
