Awtrix Shell

I designed a shell for Awtrix. Info, tutorial, electronics and links here: https://awtrixdocs.blueforcer.de/#/en-en/README The LED Matrix I used is this 8x32 one: https://es.aliexpress.com/item/4001296811800.html?spm=a2g0o.productlist.0.0.799674efnzxHgg&algo_pvid=8d158219-94d6-4fb7-a610-1fe3a8847ef9&algo_exp_id=8d158219-94d6-4fb7-a610-1fe3a8847ef9-0 I know it looks like it is a lot of filament, but I printed everything in 5% infill and 0.3 layer height and it's actually quite cheap, around 5€. Also, I have an ender 3, so I had to print everything in two parts and then glue them together using some joiners to make sure it is strong, and it actually is. I used hot glue to make sure it is also removable, in case I want to change anything, but I don't think so, since the LEDs are not going to stop working any time soon and I have easy access to all the electronics. I also used m2.5 inserts for the Raspberry and M3 inserts for the cover for this purpose. So, how to build it: 1- Print everything and glue every part together except the case. 2- The LED Matrix should fit in the holes, and the backplate it's glued behind to make sure the matrix doesn't move at all. In the end you should have a pretty sturdy stack. Beware that I had to sand down 0.5 mm of the LED plastic part in order to fit in the case. 3- Cut a piece of glass so it can fit inside the case. It is actually pretty easy. Then use (I don't know how it is called) tinted glass vinyl? The vinyl used to make the windows in the cars darker, so you can see the LEDs perfectly but not the LED plastic part. 4- Put the glass and the stack with the LED plastic part, the LED matrix and the backplate inside the cover and glue it to the cover with some hot glue and joiners. Now you can glue together the cover itself with four joiners. 5- Put the cylinders with the inserts in the corners, 3mm below the surface and hot glue them there. 6- Screw in the cover. 7- Glue the hiders in place so you can't see the line where the two parts join so it looks like one piece.
