If you want to make one of these for yourself you can use this design as it is or and alter it and make it better.
If you just want one, see the PDF file for the digikey order IDs of the parts and here is a place where you can order 3 of these (bare boards) for $6.30 including shipping (I don't get a penny of that by the way. I just think it is a decent deal):

The 12 most common of 13 parts.
It measures 51 × 15.5 mm and has 2 copper layers, 1.6 mm thick.
13 parts, built around the AZ1117CH-3.3TRG1 and 10118194-0001LF. 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.
From the johnwinans/2044-breadboard-power repository on GitHub, at the commit this page was made from: the board is 2044-breadboard-power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask johnwinans before reusing the design.
