Description
(UPDATE)
I've added V2 versions of the mount and holster This will help with printing and strength.
A Major problem with v1 is the neck of the part is very weak due to the orientation while printing. The V2 version is smaller but a lot stronger because it can be printed laterally. Also I've changed the solar rest to be 2 pieces with an opening rather than one closed piece, this is so the print can be replaced without removing the pigtail from the circuit board. The N-Type hole has also been widened for easier insertion.
Two v2 holsters have been added. One with a flat back for wall mounting and one with a curved back for tree mounting. The rounded bottom has also been cut to allow for vertical printing with no supports.
The new mount can also fit into the old v1 holster if you already have that mounted somewhere.
Instructions
This is another iteration of the Meshtastic Harbor Breeze off-grid solar mod. I created this bracket to support an N-Type connector that is sturdy enough for a large N-Type antenna. I've also created an SMA versions which can be found here:

Assemble:
Remove the Solar panel from the lawn spotlight and open it up. Cut spotlight LED wires and remove.
(rak) stick self adhesive ble antenna
To be able to use the native (on/off) switch on the panel, solder positive and negative leads to a JST connector shown in picture below:
Print the bracket, I printed using petg-hs and no supports
Place the lock ring and rubber gasket on the N-Type connector and place the connector through the keyed hole of the mount. Tighten the nut to secure.
(optional) Apply heat shrink tubing to pigtail wire if worried about damage from the elements.
Run the pigtail between the rest and into the solar housing using the existing hole (hole was previously used for LED on spotlight)
Use existing nut and bolt to secure the solar housing to the mount. The panel can be angled up and tightened if needed, the rest is used in case of fatigue over time. It should be at a pretty optimum angle.
Connect both Pigtail and blu ipex connections.
(optional) Swap out 1500mah 18650 battery for a higher capacity one.
Close the solar housing with original screws
Print out Holster.
The holster was designed to be screwed into (or double sided taped onto a surface. It's keyed design allows for the entire panel and antenna to slip into easily and removed just as easily for maintenance.
Slip the mount with equipment attached into the holster.
Power on by pushing the (on/off) button on the back and you are ready to rock n' roll!
