README

Off The Shelf Drag Chains for 2.1

Note: Tested with 300mm 2.1 build only.

Why

  • Drag chains with a snap open side are a joy to work on.
  • It looks awesome.
  • Looming up wires makes them harder to access.
  • I hate tape chains.

BOM

STLs

FileNote
x_carriage_frame_right_remodeledParametrically driven remodel of the right toolhead without the wire tray. The through-screws are modeled like the original stl, but they seem pretty tight from my printer. YMMV, you might need a tap or just start working out more.
x_carriage_dragchain_anchorpointYou screw your drag chain's floppy end to this side.
x_carriage_wire_coverCosmetic wire wrangler interfacing the drag chain to the X carriage. Mounts with a short M3 screw.
xy_drag_chain_bridgeYou screw your drag chain's floppy end to this side. Wires go through it and up into the Y chain.
a_corner_wire_guideCovers your wires around the A corner. Keeps them from chafing against the rail and frame, while keeping them tidily away from the belt. Also, you screw your drag chain's floppy end to this side.
lower_drag_chain_mountMounts to the rear lower frame. You'll need to cut an L shaped slot into your bottom panel. Also a great spot to run your bed and heater wires down through. Move this on the rail until you get a little tension on your Z chain. That'll keep it tight and it will look awesome.

Known Issues

  • I haven't accounted for the toolhead doors yet.
  • X carriage screws are a little tight. Probably "won't fix."
  • A corner guide could be a little wider in critical places without interfering mechanically with the printer. All my wires fit, but yours might not.
