Lightsaber for use with ESP8266 WiFi microcontroller

This is a modified version of https://www.thingiverse.com/thing:557812, for use in my project to light up a blade using a WiFi enabled microcontroller (the ESP8266), see

I left out the internal parts, to make room for the electronics.

I thickened some of the walls, in an attempt to strengthen it to survive some combat with my kids. I added some cutouts to make room for some components.
