very much work in progress.

idea for the contraption
will hold rak and at least two 18650s, battery sled is also designed to fit into the back of tonyg's 19007 x2 18650 case. uses these terminals www.amazon.com/gp/product/B083XTPY4C

designed to be pulled up into a tree and have solar panels on all sides, to recharge batteries, or sit flat on something and have solar panels on top to recharge.

goals / crap still left to do
make detent for solar panels, figure out a wire passthrough for solar power cables
this needs to be done for top and for middle
put in screw locations + heat set threads to positively join all pieces
maybe make different locking sleds for things using heat sets
make tpu gaskets?

test fit and finish of all the parts, make slt files with sled mounts integrated,
make a sitting version and a tree version
upload pictures
beef up clip for rak sled

printing it out of pla for test model, will print from petg with 3?4? walls for water resistance...

notes
if printing the one that sits flat you can just place rak sled.v1.stl in the bottom and print as one piece, dont think the clip i deigned will allow slotting it in from the top, will only work sliding it in from the side, and that's blocked by walls of bottom.
i designed the mounts to be placed in/on the inner walls of the middle triangle piece so the radio could be assembled and then placed inside.

inspiration from
battery sled fits perfectly in RAK19007-5005_v15_back_dual-18650_xxxxx from tonyg's design https://www.printables.com/model/286657-rak19007rak5005-case-for-meshtastic
stole the rak mount idea from this, sorta feel i improved on it, since mine will fit a 19007 or 19003. https://www.thingiverse.com/thing:6544498
