* Direct drive mod for 2.1 and 2.2. * Add example image to direct drive mod readme.md * Add assembly instructions to direct drive mod readme.md * Fix m2.5-m2 assembly instructions bug in direct drive mod readme.md * Add v6 direct drive mount. E3d v6 is reported to be 1.1mm taller than the mosquito all mounted up. This change should retain the nozzle elevation to help keep inductive probes working if someone mounts a v6 to the BMG mount plate. * direct drive model improvements * make room for extra belt * add 0.32mm seats for back side nuts * Fix support arm model bug in v6 * drop the fan nozzle outlet as low as I dare * add known issue * Add 2.2 openbuilds chain mod * added example render image to 2.2 openbuilds drag chain mod * add taller x carriage mount for drag chain mod * update openbuilds xy bridge * pull back cable chain mount 3mm +x * modify tube profile * add 1mm mouth height * add 1mm span width to curves |

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.
