EggTracker rocket tracker

A handheld rocket tracker for an eggtracker (from eggtimerrocketry.com, with upgraded antenna option) with bluetooth module, using 2x 18650 batteries. The sled is sized to hold a Pixel 4XL with thin case, so you may need to resize or customize the footer to fit your particular phone and/or glue it in a different spot. Recommend PETG and a .4mm nozzle. PLA could work if you use a lighter color and try to keep it out of the hot car and sun as much as possible.

Hardware needed:
Eggtracker and bluetooth module
2S 18650 battery holder
10-32 1in wing bolt (Home Depot)
10-32 nut
3mm x 25mm bolt and nylon lock nut
four 3mm short screws (optional, to mount PCB)
7 pan head wood or sheet metal screws, sorry I don't know the size as I had them "lying around". They're about 7/16 long and a bit over 1/8" wide.
A "mini" square toggle switch (weather resistant a good idea)
5mm LED for power indicator
Appropriate resistor (depends on your LED, but 220ohm worked for my 20ma LED)
915Mhz
