Clean

Check a custom lab part against the labware it mates with, then write the design brief and the parametric build123d model. Free in your browser: every interface dimension looked up in bundled standards (ANSI/SLAS microplate footprint, height, flange and well positions, a 10 mm cuvette format, metric and imperial breadboard grids, the 30 mm cage system, SM1 threads) and checked the skill's way - a pocket at maximum material condition plus clearance, a matching part inside the band, the process undersize budgeted; walls, features, printed holes, threads, pocket corners, grid pitch and laser kerf held to FDM, SLA, SLS, CNC or laser limits; the material held to the autoclave, the cleaning agent, cell contact and the optical path; every requirement mapped to a go/no-go gauge; a to-scale top view and a parameter block. Built on the SkillSafe skill @k-dense-ai/lab-hardware-cad, from k-dense-ai/scientific-agent-skills (MIT), by K-Dense Inc.
