Concept, to be validated in the prototype. Nothing here is tested.
Candidate parts
Each part below was checked on its maker’s own product page; the column “Maker page checked” is that page. Every line is a candidate, to confirm in the prototype. If a part number could not be confirmed on the maker’s site, it is not listed: the function shows to select.
