VoronDesign/Voron-Tap
Tap is a nozzle-based z-probe for the V2 and Trident printer designs. The entire toolhead moves to trigger an optical switch. Tap offers many advantages:
It measures 40 × 60 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the MCP1702-3302E/CB. 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 buteomont/Delivery-Box-Reporter repository on GitHub, at the commit this page was made from: the board is resources/kicad/delivery-box-reporter/delivery-box-reporter.kicad_pcb and its schematic resources/kicad/delivery-box-reporter/delivery-box-reporter.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 buteomont before reusing the design.
