This is my complete Wilson II cable management system. Will work on other 2020 frame printers and adaptable to other printers.

Note: This will loose aprox 15mm of Z axis height.

My Wilson II is 50mm wider and 50mm Higher than the STD Wilson design.

The chain is dragchain by TuxSoft, done in a customizer http://www.thingiverse.com/thing:915487

UPDATED: the holes in the X_motor_Nema_17_Wilson_Cable_Chain.stl where to large, this has been fixed.

UpDated; few extra holes on the X axis for cable ties

Added other number link files for the 8x10 and 8x20 chain links.

I use 2 x M3 cap head screws to join the X_motor_Nema_17_Wilson_Cable_Chain and Z_X_carriage_cable_chain_bracket together. I just screwed then straight into the holes as is. I used 1 self taper into the X motor ust drilled a small hole and screwed a very short srew in to hold it.

For the Y carriage I just drilled 2 holes off the part and used a zip tie. The hole is 2.5mm

My Printer I'm using

21 8x20 links for Z
24 8x10 links for X
22 8x10 links for Y

With cable chains you always need a little cleaning of some sort.

Hi Antony.

I have just downloaded the cable management files ready for printing. My Wilson II has a 300mm X, 300mm Y by 250mm Z. How many components do you think I will need for this?



Just measuring the chain it's about 8 links to 100mm.

So you would need a minimum of and extra length for X. Y is the same so that should be ok and in Z there is a 4 link length so one more of that should get you close to enough.

I have a question:
What size is your Wilson II? Would be good if you added that in description.
And a suggestion:
Adding a chamfer on the front side of the shafts on each link for easier assembly of links!?

My Wilson II is 50mm wider and 50mm Higher than the STD Wilson design.

Drag Chain with mounts

Hi, I Have printed the parts. I am Trying to figure out how the Z-X_Frame_Dragchain_8x20_male is used / mounted? Is it mounted above the stepper on the 2020 extrusion?

I have added 2 more pics the bracket goes on the frame under the board. It's very close to the motor o the Wilson 2 frame. My Z axis is about 200mm so I am using 19 links so you may need more or less depending on your frame size.

I see now, thank you. And thank you for this nice drag chain system!

The hole pitch of the X carriage plate is 23mm x 23mm so you can just measure yours. If you hole pitch is different give me the dimensions and I will make a version for your setup.

does the x carriage mount have the standard screw hole placement for prusa i3 reworks? I was wondering if this would work on my Wilson I

Don't you lose Z height with the chain sitting on top of your X axis?

Yes unfortunately you do. On the Wilson II frame there is little room to between the X motor mount to run the wires between the frame. The only other alternative is to rout them under the X motor mount. Which is a possible option and I'll look at that.

I fixed the problem a little on my new frame by using TR8 x 350mm lead screws and making the 2020 frame 50mm higher and of course the Z axis smooth rods longer.
