Design for a 3D-printed-parts storefront: item catalog with images and
quantity on hand, a transaction ledger attributing every take/restock/
adjust to a badge-scanned employee, an unauthenticated touch kiosk
(scan bin barcode, scan badge, keypad quantity), 1x0.5in CODE128 bin
labels, and stock/consumption/by-person reports.
The lab guide walks a developer through building it in seven
checkpointed milestones, reusing the USB badge contract, the
measuringtools migration baseline, the models-image upload trio, and
the open kiosk-endpoint precedents.
