This project uses an adafruit feather rp2040, an ethernet hat, and a 7-Segment Display to display the time. The project is meant to be rackmounted in 10-inch, or half rack.
All items are meant to friction-fit into the single printed part.
Install the ethernet featherwing on the feather rp2040, and connect the 7-segment display via both the i2c connector, and 3.3v power (labeled '+' and '-' on the 7seg PCB).
Optionally connect "VBUS and "GND" on the sparkfun breakout board to "USB" and "GND" on the rp2040 if you wish to have a backwards-facing usb (otherwise rails may impede the usb-c cord).
Flash the rp2040 with the provided .ino file in the repository. Some libraries are required, such as Ethernet, SPI, Adafruit GFX, Adafruit_LED_Backpack_Library.
I printed the plate on my Prusamk3s+, the .3mf project file is included, this file includes the keystone, which I did not model in freeCAD.
The part was printed in PLA, layer height was .3mm, with a gyroid infill of 15%.
I printed with no supports, but the mounting pegs for the usb-c breakout board needed to be filed to fit.
