Magnetic mount Nevermore duo for Voron V0

This is a modified Nevermore duo plenum for mounting in a Voron V0 with magnetic components for easy installation and removal. 

A JST-XH is no fun to plug in and remove in a tiny little printer frame, this is way easier once set up.

PRINT NOTES:

No support should be required, however the alignment rails on the feet, as well as the holes do print a little nicer with support.

I tried to clean up the wire retention bridges, they don't print well in the original. If they still cause a problem, cut them out, they're not necessary.

BUILD NOTES:

There isn't a ton of space inside the foot with the connector, so be mindful of your strip length, and solder them on an angle as shown in pics.

Check the polarity of your contacts before you solder the second connector, they only stick one way.

The retaining rings have a chamfer on one side, install with that side facing the connector body so they seat all the way. Remember to put the retainer over the contact in the plenum before you insert it and get glue in there. 

Once you get the screw started in the nut on the foot with the contact, lift it up and fish the wires under and along the extrusion channel to the electronics bay.

This uses 4 additional 3x6 magnets from the standard Nevermore BOM, and a standard M3 Voron brass insert for the lid screw. You'll also need 1 M3x8 and 1 M3x10 BHCS , 2 M3 hex nuts or drop in nuts if you have some for mounting the feet, some wire of your choosing, plus a 2 pole pogo pin connector pair. 

I use epoxy to secure the magnets, and CA glue for the retainer rings to hold the connectors in place.

I have tested this only in ABS

The 3mf file contains all the parts for the modified components, only geometry, no print settings. I attached the stl files in case they're better for some of you, but I haven't tested them myself, they are as generated from fusion360.

f3d file also included in case you feel like tinkering.

Feel free to reach out and let me know what works/doesnt.

Enjoy!
