Weatherproof Meshtastic Enclosure RAK19007/RAK19003 + GPS + 4x 18650 batteries

This is meant to be a stationary node, not a portable handheld device. It features:

• compartment for up to 4x 18650 lithium-ion cells (long enough to accommodate protected cells)
• M2.5 mount points for RAK19007 or RAK19003 base board
• M2 mount points for RAK19004 green power module (for solar charging)
• N-type antenna mount for main antenna
• Friction fit compartment for 28mm ceramic GPS antenna
• Waterproof USB-C connector
• Threaded hole for M8 cable gland for solar charging wires
• optional drainage hole
• Three mounting options:
  • Threaded inserts for attaching magnets
  • Elaborate and kinda awful pole mounting mechanism
  • Simple and very nice mechanism for using zip ties or other straps

The mounting system on the back of the case consists of four holes in a 100mmx70mm square and two holes in the center spaced 40mm apart (see picture). These holes do not go all the way into the case, so water can't leak through them. They are sized for M3x4.6x6mm heat set inserts.

Parts list:

• RAK19007 or RAK19003 base board with RAK4631 or RAK113100 core module
• 4x M2.5x6mm screws (come with the RAK boards)
• RAK19004 green power module (if you want to solar charge with an unregulated panel)
• 4x M2x6mm screws
• 1-4x 18650 batteries in a pack
• 10x M3x4.6x6mm heat set inserts
• 6x M3x25mm screws
• N-type to UFL cable and antenna mount
• Waterproof USB-C jack and USB-C connector (soldered together)
• M8 cable gland
• N-type LoRa antenna 
• 4x M3x6mm countersunk screws
• RAK12500 GPS module
• 28x28mm GPS antenna
• Probably something else I'm forgetting

Note that this case is weatherproof, not waterproof, even with a TPU seal. I stuck it in my shower directly in the water stream for like an hour and it was still done dry, so rain isn't gonna hurt it. However, when I submerged it overnight (without the electronics inside obviously) it filled about halfway with water, so there was a small leak somewhere. There's a small hole in the bottom of the case which you can either leave open to act as a drainage hole in case some water does get in, or you can seal it with an M3 bolt.
