JST Hub for 2020 Extrusions - Wiring Bed Fans, LEDs and more!

When adding the Nevermore air filtration system and two additional the bed fans I wasn't happy with the cable management solutions that I found 😕. I started with designing these clips for the cable routing but that left me still missing a plug-in solution for the fan cables 🤔. Using Wagos seemed to be one option but they were taking too much space. So I designed this fancy little JST-Hub 😎.

It perfectly works for managing bed fan cable connections but of course can serve other use cases as well. Let me know what you use it for an post a Make 🙂!

Support me : Please leave a Like if you actually like and use this model. It does help a lot to get some of the filament that is needed for all the test prints while creating models to share with you! And check out my other models if you're building a Voron!

Assembly Instructions

BOM

• JST-XH connectors of your choice (XH2P and/or XH4P)
• M3*8 SHC (2x)
• M3 T-Nut (2x)

Printing

Use your standard Voron settings. And I would recommend to add some support on the long bridge at the end of the hub's opening.

Assembly

Well, actually the assembly steps are straight forward (follow the pics even though they are not showing the latest version - the hub shown is missing the recess for easier opening): 

• Keep wires long enough to allow for soldering, and short enough to get them into the hub.
• Check for the orientation of the JST connectors and solder the wires on the the “top side” of the pins  - the side which is marked red in the CAD drawing. Otherwise you might have trouble to insert the JSTs into the hub.  (Click on the image to enlarge)

• And there is a diagram on the model which tells you how it is intended to connect the wires.

That's it! 😎
