Jan 2024:

Added DE V2 Version (if there is interest i could adopt for EN too)

• combined Back and inlay to one Part - for saving some printtime.
• Added / Modified Cable outlet - not a big hole but a smaller cut on the bottom back. Helps to get USB cable out more clean

Initial:

Remixed this from AWSW great model https://www.printables.com/de/model/450556-wordclock-16x16-led-matrix-2023-v3 - on github you can also get his neat Arduino Software to operate: https://github.com/AWSW-de/WordClock-16x16-LED-matrix-2023

General Information:
I only remixed DE+EN Fronts so far, other languages would take litte work if someone needs it but had no use for myself.

I love his clock in general, but I did not like those Sharp Edges in the corners, feels not good to print without warping on such a large print.
This model is printable with default Bambu settings - so much faster than original. 
Another BIG advantage is that clock can be read from sides in a much larger angle.

M3f Frames are already painted for 2 Colour AMS, you want to use white for first 2 Layers (front) and a real dark colour for the rest that Leds od not shine through.

Print:

Choose each 1x Back, Fixer and Frame in your language.

Using the textured PEI gives a real nice front, but plain plates should also work great
PLA is fine, not tested if PETG does good Job with all the letters, but should also work.

Needs following Accessories to assemble:
1)
Securing the Back Plate
4* Brazz Inserts M3xOD5xL3 (like used in P1P ARC Case)

4* 6mmxM3 screws

2)
Internals

1x RGB LED Panel WS2812B 16x16

1x AZDelivery 3 ESP32 D1 Mini NodeMCU

3)
Power
1x USB Ladestecker Adapter 5V 2A USB

1x deleyCON 2m Micro USB Ladekabel

Hardware Assembly:

• melt the brazz inserts into the frame
• flash software to D1 before soldeing as function test
• cut not needed "out" cable on the RGB matrix (if ou wan it clean unsolder the +/- cables too)
• solder this cable to D1 mini (pic attached)
• press fit D1 Mini on Back, to be sure it holds attach some hotglue
• Connect with matrix using the cables
• put matrix in Place (see picture for orientation) and secure it the RGB-fixer
• Close back and softly fasten with 4 screws
• Power On and bind your Wifi
