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,
