Component catalog

All registered component kinds. Parts you can place in a bench.

• `shaft` (mech) — Cylindrical rotating axle. Typically anchors one or more gears via mech.couple so they spin together.
• `spur-gear` (mech) — Cylindrical gear with straight teeth. The canonical mechanical building block: mates with other spur gears of the same module via mech.mesh.
• `pulley` (mech) — Smooth rotating disc used as a belt anchor. Pairs with another pulley via mech.belt; the ratio is driven by the pitch diameters.
• `htd5m-pulley` (mech) — Synchronous timing-belt pulley with the HTD 5M profile (5 mm pitch, curved teeth) and optional side flanges. Meshes with HTD5M timing belts; 3D-printable.
• `rack` (mech) — Straight toothed bar. Engages a spur gear (the pinion) via mech.rackPinion; the pair converts rotation into linear translation along the rack local X axis.
• `bevel-gear` (mech) — Cone-shaped gear for transmitting rotation between intersecting axes. Two bevel gears of the same module mesh with their axes meeting at pitchAngle_a + pitchAngle_b (usually 90°).
• `helical-gear` (mech) — Cylindrical gear with teeth cut at a helix angle. Quieter engagement than a spur gear; meshes with another helical of the same normal module and equal helix angle with opposite hand on parallel axes via mech.helicalMesh.
• `crank` (mech) — Rigid arm that rotates around a pivot. The pivot sits at the component origin; the arm extends along the local +X axis for length mm. Same single rotational port as a shaft, different visual footprint.
• `motor` (mech) — Rotational source. Produces a constant RPM on its axis port every tick; connecting a shaft or gear via mech.couple / mech.mesh drives the downstream chain.
• `sprocket` (mech) — Toothed wheel that engages a chain without slipping. Pairs with another sprocket via mech.chain; the ratio is driven by tooth counts (not diameters, unlike pulleys).
• `worm` (mech) — Single- or multi-start helical screw. Pairs with a spur gear (the worm wheel) via mech.wormMesh for very high reduction ratios (typical 1:20 up to 1:100).
• `steel-tube-square` (static) — Hollow square-section steel profile — the primary structural member for benches and frames. Runs along its local Z axis; rotate it to stand or lie as needed.
• `steel-tube-rectangular` (static) — Hollow rectangular-section steel profile for frame rails and stretchers. Section w (X) × h (Y), length along local Z.
• `steel-sheet` (static) — Flat steel plate. Lies flat: length along X, width along Z, thickness along Y. Use as a metal worktop, gusset, or base plate.
• `wood-panel` (static) — Flat wood board — OSB, MDF, plywood or pine. The classic bench worktop or shelf. Length along X, width along Z, thickness along Y.
• `steel-angle` (static) — Equal-leg L-section steel bar for brackets, gussets and reinforcement. Cross-section leg × leg, length along local Z.
• `bolt` (static) — Simplified metric hex bolt: hex head plus plain shank (no thread modeled). Runs along local Z, head at the +Z end. For fastened joints and the BOM.
• `generic-solid` (static) — Neutral rectangular block used as a bounding-box stand-in for parts that do not yet have a dedicated kind (round bar, channel, custom profiles). Sized width (X) × height (Y) × length (Z), centered on the local origin.
• `steel-flat-bar` (static) — Solid rectangular steel bar (barra chata) for braces, straps, feet and gussets. Width along local X, thickness along local Y, length along local Z.
• `steel-tube-round` (static) — Hollow round-section steel tube for handrails, legs and light frames. Runs along its local Z axis; rotate it to stand or lie as needed.
• `steel-channel-u` (static) — Open U (channel) steel section — a stiff cross member. Web along local X, flanges rising along local Y, length along local Z.
• `caster-wheel` (static) — Swivel caster: square mounting plate + steel fork + nylon wheel. Bolts under a leg or a base frame so the assembly rolls. Plate faces up (+Y), wheel touches the floor (−Y).
• `leveling-foot` (static) — Adjustable foot: a round base pad and a threaded stud that screws into a leg to level a bench on an uneven floor. Pad at the bottom (−Y), stud pointing up (+Y).
• `hinge` (static) — A flat steel butt hinge: two leaves and a knuckle pin. Shown open and flat — leaves span local X (width), pin runs along local Z (length), thin along local Y.
• `handle` (static) — A tubular U-shaped pull handle: a grip along local X standing off the surface by its two legs along local Y. For drawers, doors and lids.
• `drawer-slide` (static) — A telescopic steel drawer slide. Runs along its local Z axis; the section is width (X) × height (Y). Comes in pairs (one per side).
• `profile` (static) — A custom 2D polygon extruded along local Z — for gussets, brackets, mão-francesa braces and cut plates. Points are [x, y] pairs in mm, authored counter-clockwise; the shape is centered and extruded by thickness.
• `custom-part` (static) — A part you drew in the sketch/body editor (the parts library) placed into a bench. It carries a reference to the saved body plus a denormalized snapshot of its bounding box, weight and material, so the bench renders the real evaluated mesh while its graph, layout and BOM stay self-contained.
