Overview
Milk crate is an open-source printed circuit board by somepin, from the somepin/milk-crate repository on GitHub, published under the MIT licence. It is a 2-layer board of 35 × 50 mm with 6 parts on 22 nets, routed with 18 tracks and 0 vias.
Its parts include 2 connectors and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

Another milk-themed meme board, for your extra unused base kit/novelty ISO keys. Inspired by Spaceboards/2% Milk.
Build Notes
Printing
Print upside down slowly at ≤0.2mm layer height, with supports enabled.
Assembly
Essentially the same as 2% Milk. I reccomend flasing the firmware to the Pro Micro before assembly.
- Put switches into the top of the case. With the port on the left, the left switch is north facing, and the right switch is south facing.
- Break apart the headers to only use the required pins in the diagram below.
- Solder short header pins to the side that says "GET SOME MILK". The plastic headers should be on the "MILK CRATE" side.
- Insert stabilizers into the PCB. Hook side goes in to the big hole, clip/screw goes into the small hole.
- Optionally solder RGB LED to the broken out RGB pins.
- Insert the PCB into the case, then solder the switches.
- Solder the Pro Micro to the header pins, making sure that the electronics are facing up.
- Install ISO keycaps, and enjoy :)

Questions
How big is the Milk crate PCB?
It measures 35 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Milk crate use?
6 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Milk crate KiCad files?
From the somepin/milk-crate repository on GitHub, at the commit this page was made from: the board is kicad/milkcrate.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Milk crate design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
