Meshtastic FakeTec case with battery 503450 and spiral 868mhz antenna inside.

Meshtastic case sized of a car alarm keychain. Key idea - make cheap keychain meshtastic node - always with you. You connect it, charge it, sending/reciving messages... thats all. No place for buttons or attachments - just basic functions.

Fit: - FakeTec v5 node on nrf52840 (promicro) - small LiPo battery 503450 - internal spiral antenna (selfmaded with attached template) Print settings: PETG, no support needed.

The antenna is mading by winding 5mm thick wires onto an antenna template. Then antenna+template construction mounting into front case at corresponding mount. Antenna template founded on article https://e.pavlin.si/2018/06/29/small-normal-mode-antenna-for-868mhz . VSWR of assembled construction hadn't measured (I have no nanovna). If someone can measure VSWR and adjust construction - give feedback, please.
