Case for LED display with STM32 and MAX7219 LED driver.

Hello, this time i want to share a new thing i built yesterday. It is a case for a led matrix display controlled by a stm32 microcontroller.

UPDATE 2. 05.03.2017: Now you can download the software to run the led display from my blog: http://www.ingenieriaencasa.com/2017/03/software-para-pantalla-led.html
You can find too an explanation video of the code and how to prepare the stm32 board on my youtube channel: https://youtu.be/4maNR0mGTns

UPDATE 1. 01.03.2017: i did some minor changes in the part Case_Matrix_M.stl to fit better the STM32 board. The new one is Case_Matrix_M_v2.stl
