Galileo 2 PG7 Cable Gland Mount - FITS Voron 2.4! M12 too!
Manage your Galileo 2 Cables SECURELY!
Recently I installed the Galileo 2 Extruder assembly on my Voron 2.4, but I had an issue mounting my CAN Umbilical cable. The files for the G2E include a PG7 mount, but it mounts behind the Extruder Motor. On a Voron 2.4 this means it hits the Z-Cable Chain & in my case, my Umbilical Mount on the rear Gantry. It seems to be made for Tridents with the cable going through the vent opening only. So I made this mount! It mounts to the left of the Extruder motor and provides a clean back that has no interference issues with the existing Voron Design V2.4 parts.
Files include 2 versions of both a PG7 mount and a M12x1.25mm Mount. One version is standard design, the other has a slot so you don't have to feed your umbilical cable through the mount. I needed this so I could easily swap my cable setup without having to rewire my entire CAN cable & resleeve it. The “Split” versions use a single M3x12 screw to add some rigidity to the opening after you install your wire & cable gland.
This design also uses a 20mm spacer design (the HartK one used 17mm), which should allow just enough room to fit a wire or two between the motor & the mount. I've included a 20mm printable standoff, but I really recommend aluminum stand-offs, easily available on Amazon and from Hobby Shops (common in RC stuff).
NOTE: As this mounts to the motor mounting screws, and the Galileo 2 has a "floating" motor design, this MAY cause some tensioning issues if your umbilical does not have enough slack. Be mindful of how much tension is on your umbilical cable when assembling! I haven't had any issues yet, but I could see it being a problem if the cable is pulling tightly.

Must say, I watched your videos of CANbus setup and it was great! Even better that you just came out with the PG7 for Galileo2 literally the night I needed it. Any chance you have a hex door cover for the new Galileo2?
Hi, sorry I missed this comment. I actually did make a Galileo 2 version of my Hex Door. I'll upload it as soon as I wrap up my current project (so later today hopefully).
Good evening- I ended up starting over and doing something similar but mounted to the extruder mounting locations that are stock for the Galileo 2. I uploaded the model here if anyone has the need. https://makerworld.com/en/models/642550#profileId-568514
I found this one to perform quite bad with input shaper, can you maybe add a thicker version? Also the slotted version screw broke my mount with only slight pressure, maybe this could also use some work. Nevertheless, I like this mount for PG7 the most, thank you for that!
If still needed.

You might just be my savior for me doing my first ever build. I probably didn't think far ahead being my first ever build, but it looks like you might have made all I need, I'm making a Voron 2.4r2 300 and have gotten the BTT SBB2209 (RP2040) CAN, Galileo 2 and planning on using the Linneo umbelical for it. Just now when I looked at the parts BTT suggested to print they weren't at all for Galielo, and the Galileo parts they want printed doesn't seem to have the mount for the umb/chain.
I designed something similar and abandoned the idea. The simple reason is that the motor is quite heavy and mounted on a levered part that is spring-loaded. Any variation of weight or pressure on that assembly is going to reflect on the pressure on the gears that drive the filament. Visualise the CAN cable being whipped about the printer and the radius of the bend is not going to be consistent. That translates to varying pressure on the filament drive system.

A reasonable concern I had as well, but I have not seen any issues in reality. I've put about 150 Hours on the machine with G2E & this mount, with NO noticeable affects. My Z-Axis of parts has some inconsistency, but no more than it did with ClockWork 2, and possibly less. I noted in the description, the tension of your Umbilical cable could be an issue. I made sure I had plenty of slack to not tug on the toolhead at any point in the movement and it hasn't caused a problem I am aware of.
