For labs that print, mill or cut their own hardware
Part FitA holder 0.5 mm too wide does not fit the plate reader. Check every mating number first.
Describe the part, then list what it mates with. Your browser looks each interface up in the bundled standards and checks it the way the skill does: a pocket at maximum material condition plus clearance, a matching part inside the band, the process undersize budgeted. It holds walls, holes, threads, corners and the table grid to the process, the material to the autoclave and the cleaning agent, and turns every requirement into a gauge. Then the brief, and the build123d model.

How it works - and what is sourced
The checks follow the skill. The hard part of lab hardware is the mating dimension, not the geometry, so every interface number comes from a bundled standard - the ANSI/SLAS microplate footprint, height, flange and well positions, a common 10 mm cuvette format (marked unverified: use the catalogue drawing), the metric and imperial breadboard grids, the 30 mm cage system and SM1 threads - or is named as unchecked. A pocket is sized from the mating part's maximum material condition plus clearance; its own process undersize must still leave a gap.
Clearances per side are the skill's first-article defaults: free-sliding 0.40 mm on FDM, 0.20 on SLA, 0.10 on CNC. Printed holes come out small; printed fine threads fail; a mill cannot cut a sharp internal corner, and a fillet larger than the plate's 1.58 mm minimum corner radius binds. PLA, PETG, ABS and resin do not survive an autoclave; acrylic crazes on ethanol; resin should hold, not touch, cells. Print a test coupon of the critical interface before the full part. The page checks numbers and the structure of the model code; it does not build the part, so check every dimension against the catalogue drawing before fabrication. Part Fit is a planning aid, not engineering sign-off.
