Single pcb for Cherry ULP switches
Amoeba ulp is an open-source printed circuit board by jonboh, from the jonboh/amoeba-cherry-ulp repository on GitHub. It is a 2-layer board of 18.2 × 16.8 mm with 6 parts on 3 nets, routed with 15 tracks and 3 vias.
It is built around the 1N4148WS.
Single PCBs for the Cherry Ultra Low Profile switches.
I used these to make my ULP Dactyl.

TobleMiner/DC-UPS
A small DC UPS, designed to keep small appliances like consumer network equipment running during power outages
It measures 18.2 × 16.8 mm and has 2 copper layers, 1.6 mm thick.
6 parts, built around the 1N4148WS. 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 jonboh/amoeba-cherry-ulp repository on GitHub, at the commit this page was made from: the board is amoeba-ulp.kicad_pcb and its schematic amoeba-ulp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask jonboh before reusing the design.
