I configured my setup with a RAK 1W unit in the XL side for Meshtastic and a RAK19003 in the Small side for Meshcore.  I made a splitter for the battery that runs to both RAK's.  Solar panel just plugs into the RAK 1W.  I have had 0 issues with the battery charging, and with the solar plugged directly into the RAK, meshtastic correctly reports battery charge and state.

Assembly should be straight forward. I ended up printing the shell outside down at a 40deg angle with the solar mount lip toward the bottom. The support issues I had with the grey print turned out to be the filament.  I got Elegoo ASA in white, and the results were much better.  I got better results with normal supports than with tree supports.

While the machine screws show a little surface rust, the inside has been perfectly dry through several hard showers without using any sort of gasket or sealing material.
