Hardware Catalog
This page is the cross-reference for fasteners, threaded inserts, bearings, and other hardware that are reused across multiple parts. Where a printed part’s BOM in the Parts Catalog references a hardware ID, that ID is defined here.
Hardware is grouped by category. Each item has a unique ID and a single canonical entry - multiple printed parts that use the same insert or fastener should reference the same hardware ID rather than restating the spec inline.
Note
This catalog is currently seeded with the hardware referenced by the first generation of printed parts. Additional fasteners, T-nuts, bearings, and rod-end ball joints will be added soon.

Fasteners
To be populated as fastener sizes are finalized in each printed part’s BOM. Anticipated entries include:
M3, M4, M5 socket head cap screws (multiple lengths)
M8 cap screws + matching T-nuts for 4080 extrusion
Shoulder bolt for the rocker differential arm vertical pivot (TBD)
Bearings
Motor-shaft radial bearing (motor bracket press-fit) - bore TBD
Frame-ear pivot bearing (chassis frame press-fit, rides on hollow rod stub OD) - bore TBD
Linkage Hardware
Ball-joint rod ends (used on both ends of each pushrod, mixed orientations)
Threaded rod stock for pushrods
Jam nuts for pushrod adjustment locking
Source of Truth
Quantities listed in this catalog are per-piece unit costs as of May 1st, 2026. The total hardware cost for any single printed part is shown in that part’s detail panel in the Parts Catalog. A robot-wide rollup will be added once all part BOMs have been finalized.
