Sensor Sphere Box

I've made this sphere box in order to have my own smart home which is looks nice.

I'm using 18650 battery to run arduino code on Wemos or NodeMCU inside.
There's also a place for micro USB port to charge battery using small charger ordered from aliexpress. (will attach pictures and components soon)
Currently this sensor box (sphere) upload temperature and humidity date to cloud server every 20 minutes and goes to sleep. I'm working on power consumption reduction cause so in current state it draws battery in 1 week.

It's better to print bottom part with 0.1 resolution and for top it's from 0.1 to 0.15 cause with 0.2 there's issues for me to screw them together.
