Printed spare parts

Several parts of the G1 are themselves 3D printed. If one breaks, reprint it rather than wait for a shipment.

Click any part to rotate it in 3D and check it against the one in your hand before you print.

Before you reprint

Check what actually failed. A part that breaks a second time is usually reporting a load or an alignment problem, not a weak print. The Z power-chain support in particular breaks when the gantry is rested on the ground without care — see Transporting the G1
Do not remove factory-calibrated metal parts. The probe arm E21 mounts to a metal arm calibrated at the factory. Replace the printed arm only — see Bed leveling system
Print orientation matters on the thin brackets: a part loaded across its layer lines will break there again
