LED Matrix and Nodemcu stand

Just a quick solution to provide some diffusion, stand the matrix up and hold the MCU.
Printed in white PLA, I used 0.28mm layer height and plenty of light gets through the single layer front.
2 x 3mm (x 7mm? long) bolts hold the NodeMCU (note: V3 used) to the stand as I wanted a stand alone option for other jobs, the stand holes are 2,5mm and designed to be tapped, the nodemcu part has 3mm holes.
The LED matrix was designed to have a rear but the matrix is a tight fit and is not falling out, need to tug by the wires to remove. Not going to bother for the moment.
This is made for a chinese LED matrix, it uses WS2812B leds on a 10mm pitch exactly, overall matrix size is 80.0 x 80.0mm.

Note I removed the excess wires and resoldered the input wires .. this matrix has a great deal of heat transfer ability (aluminium substrate maybe) and this killed the LED directly under the wires, I had to swap it with the last LED on the matrix, hence the one black corner .. so be warned if you wa
