Im running a PWNCNC 2.2kw water cooled spindle on my Altmill and am finding no room for in the Cable Drag Chain for the two cooling lines. I’ve seen several 3d printed designs that hold the water lines next to the cable chain. However all of these that I have seen hang out well past the y rail into the work area of the CNC. Id like to minimize this by stacking the lines one on top of another. I have the 3d printed file for the photo below and the owner has given me permission to modify and manipulate the file however I please. I asked him to make the modifications but he’s too busy with school and 5 ap classes! If anyone wants to attempt what I want to achieve (see second crude picture) I’d be more than happy to share. Im too busy learning Gsender and Vcarve to learn 3d modeling at this time though it is on my bucket list! Ill be running a rapid change ATC and want to located it right next to the left Y rail. (photo 3) And as you can see as it is now the outer tube clip is in the way of making that a reality. Thanks
Silly question but why not point the clips to the opposite (outside) side?
@Jens I think they’d hit the plates in the x gantry
Did you see these: 💨 Ultimate Tube Clips for Onefinity Cable Chains – PwnCNC
You can clip 4 tubes but can use only the inner top and bottom slots.
I did purchase those from PwnCNC. They actually stick out into the work area further by about a 1/4” Plus they were made for the Onefinity cable chains and they needed to be modified slightly to fit over the clips in the Sienci drag chains. If I recall, I had to remove about .050” off one side of the feet so they would slide over the Altmill drag chain clips. Oh i see what you were getting at. Unfortuneately the slots on the bottom were made for air lines for an air powered atc and they are much smaller than the water tube lines up top
@Headshop if you send me the file, I’ll see what I can do in Fusion. It’s a simple enough part ….which is good, because I’m a novice with Fusion.
Awesome! I know the original designer used onshape to model this. Here is the file: https://drive.google.com/file/d/1T5x1ebkKNTMdZOVzqsPFnY6oDI5lsdMW/view
and here is the file in onshape:
You can do whatever you need to to get the tube holders stacked one on top of another with one pointing up and one pointing down. You can even make it look less like a cyber truck if you want! lol. If you feel that there isn’t much “meat” for the clips, I have measured this and you can build out to the left 1/16” where it over hangs off the chain. The gap there is a little over 1/8” over hang between the foot and the edge of the drag chain. Of course the outside dimension for the cooling hose is 3/8” or .375 but when I measure the diameter on the actual part it comes in at .350 However the diameter on the PwnCNC tube clips come in at .366 and that is still a snug fit but easier to clip the lines in place. I’m using super ethane hose so there is some give there.
yeah something like that would almost work but it would have to attach to the drag chain locking clip not encompass the entire drag chain. you want your drag chain to lay in the shallow groove on top of your y and x rails.
Wow.. You are fast! That looks great. Id need to print a test part out to know for sure to make sure my clearances are good!
funny it was changing as I was looking at it! the softened corners showed up. This came out even better than I imagined!
@Headshop Anyways, here’s the STL file. Fusion can only export to STL, not Step.

LOL, I changed the drawing. I didn’t see the slot in the original. I’ll have to put that in I think
you mean the slot that the drag chain clips slide through?
yeah, the slots are missing oin the file. Just loaded it up in bambu studio aand its solid underneath. That T slot allows the clip in the drag chain to slide through and lock it onto the chain when the clip is secured
I appreciate the work you are doing and so will many others that follow that will have the same problem. I need to head for a few hours. no rush adding the t slot back in either. Just post the file again when its done and ill do a test print to see if it will work. It looks spot on other than the t slot! tip my hat to you
Two versions of the file: one with 9.0 mm hole for the tube and one with 9.5mm (3/8”)
Tube_Holder_Headshop.stl (665.9 KB)
Tube_Holder_Headshop_9.5mm.stl (665.5 KB)
Oh Man! you’re the best! Ill print both and see how they work out.
Another version with the tubes on the side. FYI, in Fusion, once you have a 3D part constructed from the 2D drawing (they’re called sketches in Fusion), any changes to that sketch are automatically reflected in the 3D part. So to go from the part I did this afternoon to this new one took about 5 minutes of work, if that. So if you need any changes because of tolerances, let me know. It’s not a lot of work.
