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
- Some M3 screws
- A few M5 screws that are a couple millimeters longer than the M5's on the gantry. You'll figure it out.
- 3x Openbuilds 10x15mm 18mm radius Drag Chains
- All these stls
STLs
| File | Note |
|---|---|
| x_carriage_frame_right_remodeled | Parametrically 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_anchorpoint | You screw your drag chain's floppy end to this side. |
| x_carriage_wire_cover | Cosmetic wire wrangler interfacing the drag chain to the X carriage. Mounts with a short M3 screw. |
| xy_drag_chain_bridge | You screw your drag chain's floppy end to this side. Wires go through it and up into the Y chain. |
| a_corner_wire_guide | Covers 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_mount | Mounts 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.
