I remixed this from the two listed sources.
- Two types: 1) for vinyl siding 2) for everything else
- added weep holes for drainage
- added spot to insert metal plate for magnetic mount to add stability
- added screw holes
The wall mount can be mounted with double sided tape or screws, or to vinyl siding.
- enlarged hole in back to accommodate USB daisy chain
- added insert to improve weather proofing
