MrWraith's Complete Ender 3 V2 (3V2) cable chain collection

thingiverse

I've designed and adjusted lots of different cable chain stuff over the last few years, and I figured I should package all the little changes I have made into one Thing. UPDATE May 2023: I added a version of the extruder mount that works on the stock extruder, so now the stock extruder and the dual gear extruders are supported. # Looser chain links I found that all the chain links I found on thingiverse were just a little too tight - they didn't move as freely as I'd like. So while my chains are based on johhniewhiskey's original chains (and norp's slim x chains), I've made small changes to them to make them move more easily (and more quietly). These work with the same link covers as the original links. - `looser_chain_link.stl` - `looser_slim_chain_link.stl` If you find these too loose, I have included the original chain links, at `original_chain_link.stl` and `original_slim_chain_link.stl`. # Rear chain mounts To start the chains from the cables that come out the back of the Ender 3 V2, there is my design `3v2_rear_chain_mounts.stl`. This is mounted with two M5x12mm bolts, although at the original thing there is a friction fit version that doesn't require bolts. These take the cables out from next to the power switch, and send both of the chains (bed and Z) upwards. # Bed mount and Y Chain. I use the bed mount from johnniewhiskey `bed_mount.stl` and `bed_mount_cover.stl`, no changes were needed there. I use my looser links with covers, 14 chain links seems the right number for me. # Z Chain I found that the very long Z chain took up too much space behind the printer, so I have it separated into two parts, using two of benawhite's designs to help with this. From the rear mount, I have 7 links, and then I terminate that part of the chain with `chain_link_terminus.stl` (which is johnniewhiskey's `cableChain_XendCover` renamed). The cable then continues through into another chain, starting with benawhite's Z-Axis Cable Chain Stepper Mount `z_axis_stepper_mount.stl`, which connects to the stepper with two M3x6mm or M3x8mm bolts. There are then 16 more chain links, ending by connecting to the Z part of the X gantry using another of benawhite's designs. This does not require any bolts, and is a great design I think. `z_gantry_mount.stl` and `z_gantry_mount_shims.stl` (these are three different shims, the largest ones worked for me). # X Chain The X chain uses a slimmer set of chain links, from norp's design. I also use norp's hotend mount. Firstly, my design for the extruder chain mount `stock_extruder_chain_mount.stl` or `dual_gear_extruder_chain_mount.stl`, which clips around the extruder motor / extruder and has a mount for the slim x chain to connect to. Then 16 slim chain links, and ending with norp's hotend chain mount, which clips over the roller standoffs on the hotend gantry mount `hotend_mount.stl`. There are some slightly different versions of the extruder chain mount at https://www.thingiverse.com/thing:5932605. # What to print (my configuration): Rear mount: - `3v2_rear_chain_mounts.stl` Bed chain: - 14x each of `looser_chain_link.stl` and `chain_link_cover.stl`. - `bed_mount.stl` and `bed_mount_cover.stl`. Z chain: - 23x each of `looser_chain_link.stl` and `chain_link_cover.stl`. - `chain_link_terminus.stl`. - `z_axis_stepper_mount.stl`. - `z_gantry_mount.stl` and `z_gantry_mount_shims.stl`. X chain: - `extruder_chain_mount.stl` - 16x each of `looser_slim_chain_link.stl` and `slim_chain_link_cover.stl`. - `hotend_mount.stl`. # Single z-chain version The same as above, except print 25 links for the Z chain instead of 23, and you won't need `chain_link_terminus.stl` or `z_axis_stepper_mount.stl`. I used to do it this way, but since my printer is up against a wall behind it, the solution that stops and starts around the z stepper is better for me, as the chain is kept from flopping out the back this way. # Alternative with no bolts needed The rear mount for the back of the printer has a friction-fit version `3v2_rear_chain_mounts_friction_fit.stl` (It sounds like this is too loose for most people, so might need to be buffered with some tape). If you don't have M3 bolts to mount the Z stepper chain mount you can use do the single z-chain version described above. # More Z-range I realised after posting this that my dual-z setup limits the range of my z-axis, and my cables are configured for this setup. If you want your Z to go all the way, obviously you'll just need to print some more links for the Z chain. This will probably take up some of the slack from the first part of the Z chain, you could probably just move some chain links from the first step into the second step.
