This is an attachment to easily add a 20x15mm cable drag chain to the X gantry of most HyperCube Evolution extruder mounts, so you can keep all the hotend wires nice and neat. It will work with any extruder mount that is similar to Scott3D's original mount (with a tall 'tail' that the part cooling fan gets screwed in to.)
I have fitted it to both Scott3D's original mount, and einarms' Chimera mount, with no problems.
I have two different sets of these uploaded, one is for the drag chain I used (an Aurarum cable chain available here - www.aurarum.com.au/accessories/674-cable-drag-chain-20x15.html), and the other is a generic blank that you can edit in TinkerCad to add mounting screw holes for your particular drag chain.
Note the pictures are of an earlier version of the design, which used a different cable chain, and an inferior (weaker) frame mount which made cables susceptible to getting cut by sharp extrusion edges, if the drag chain was mounted on the front side (rather than the back as pictured)
A high infill is important on the frame side adapter, at least for PLA. Otherwise you might overtorque the securing screw and crack the adapter.
You will most likely need to make a small edit to the blank adapter, in order to add screw holes for your particular cable chain. In order to do this:
- download the blank adapters
- carefully measure where your cable chain's mount holes are
- Import each blank adapter's STL into TinkerCad
- create some 'hole' cylinders of 3.5mm diameter and place them where they should go on the adapter
- select all the parts and group them together
- export your TinkerCad project as STL and print away!
Installation on the gantry side involves:
- remove existing part-cooling fan
- if the part-cooling fan screwhole isn't straight through, drill it out
- press the gantry side adapter in from behind
- reinstall the part-cooling fan. You will need a longer M3 screw than last time, I use M3x30
- Secure the sandwich with a screw, or (my preference) a wing-nut for easy removal
Installation on the frame side involves:
- place on the rear-right corner of the HCEvo frame
- secure to frame with a T-nut, like most other bits of the HCEvo
The adapter is meant to cover the entire rear-right corner, including the upright extrusion. That way all the cables exiting don't have the possibility of snagging or getting cut on the edges of your upright extrusion, which may be quite sharp.
Installing the cable chain involves using an M3x10 screw through the drag chain's mounting holes and the adapter, secured with a nut on the other side. I recommend using a Nyloc nut as standard nuts have a tendency to loosen over time with all the vibration it's subjected to.
