Placeholder for the M3s whose head type and length nobody has written down yet: the cable-mount cage bracket, the camera extension, and the two board mounts.
Neither the head type nor the length is recorded — measure before ordering.
6mm Secures the limit switch hammer into the top interface chute mount from below, into the hammer's M3 insert.
The ×1 is the top-interface count (limit-switch hammer). Screws used elsewhere on the machine aren't tallied here yet.
10mm Fastens the outer cable clamp into the top interface chute mount, and the ribbon cable clamp to the cable cage bracket.
The ×3 is the top-interface count (2 cable clamp, 1 ribbon clamp). Screws used elsewhere on the machine aren't tallied here yet.
8mm The workhorse M3 screw — used all over the machine wherever a flush head is wanted.
12mm The long M3 countersunk. Used all over the machine.
20mm Joins the C-channel light post to the NEMA bracket. Threads straight into the printed post — no insert, no nut.
16mm Bolts the NEMA 17 stepper to the NEMA bracket. 3 per C-channel.
6mm Holds the layer adapter board down on the chute core's heat inserts.
12mm Mounts the cable clamp to the interface, and the limit switch to its housing.
35mm The single long screw that clamps the two cable-clamp halves together.
6mm Fastens the printed PSU housing to the power supply's own case threads.
12mm Bolts each lazy Susan together — 4 a side, through the M4 inserts in the static half and the chute mount. 2 lazy Susans per machine.
12mm Holds the NEMA 23 stepper onto the interface bracket.
16mm The most-used M5 in the machine: every external bracket, every bin bracket, every interface rib, every lazy Susan extrusion mount.
Designed to self-tap into printed plastic wherever it lands in an external bracket or the upper fixed section — no nut and no insert there.
20mm Mounts the chute limit switch assembly to the interface frame, into T-nuts.
30mm Attaches the cable cage to the six interface brackets.
35mm The long screws that stack the cable cage together, and that bolt the plywood top plate down onto the interface brackets.
8mm Loosely fixes the limit-switch interface bracket's extrusion into the interface rib while aligning it, into a T-nut.
A snug fit here, it barely reaches the T-nut. Opening the countersink a little and tightening firmly gets the head to sit flush. The ×6 is the top-interface count (1 per interface bracket); screws used elsewhere on the machine aren't tallied here yet.
22mm Bolts the interface bracket assembly and all six interface brackets down through the laser-cut top plate (holes S2/S3, then I1–I6 and O1–O6).
The top plate's laser-cut holes aren't countersunk, so where a flush head won't seat an M5 × 20 button head is used instead. The ×14 is the top-interface count (2 to the top plate, 12 through the bracket holes); screws used elsewhere on the machine aren't tallied here yet.
Placeholder for the three electronics mounts that bolt to the frame. The length has not been measured yet.
Length unknown — measure one on the machine before ordering. Six are used: PSU box, control board mount, Orange Pi mount.
Flat/fender washer, 15 mm outer diameter. Sits under the M3 × 35 button screw that holds the interface idler gear onto the NEMA 23 bracket.
The ×1 is the top-interface count (under the idler-gear screw). Washers used elsewhere on the machine aren't tallied here yet.
Plain M3 hex nut. Backs the camera-arm screws and the cable clamp's long screw.
Plain M5 hex nut. Holds the cable cage's six long screws on.
Every button-head M5 screw that goes into extrusion lands in one of these.
Bought as a length and cut down. One 4 ft rod yields all four ~1 ft pieces the two overhead camera arms hang from.
ruthex RX-M3x5.7 brass heat-set threaded insert. The default M3 insert anywhere one is called for.
The default M5 insert anywhere one is called for.
Lazy Susan mount only.
Stands the control board and the Orange Pi off their brackets.
Length is the BOM sheet's 10 mm and has not been confirmed against the board mounts.
