Switch 2 Killswitch Joy-con Grip

This is a magnetic grip for the Switch 2 Joy-cons after the Dbrand Killswitch 2 case has been put on, since they no longer fit in the grip that came with the console. I also gave the grip a slant, because Nintendo doesn't seem to understand biomechanics, and I find this much more comfortable than parallel.

This is a single 3D printed part, with 12 6x2mm magnets to hold the controllers in. The joy-cons aren't quite friction-fit, it does require the magnets. The fit is close enough that the controllers stay in decently well, but it is still relatively easy to pull them out of the grip if that is your intention, Nintendo must have used some pretty strong magnets in their official grips. The 12 magnets should be put in in alternating polarities for the sections of 3, to maximize the field strength (take the stack of magnets and make the outer two the same, then flip the middle one). I did have to superglue in some of the magnets, whether they friction-fit or not will depend on your printer's tolerances.

I've also included the .f3d file, if you want to take it and change the magnet holes or the angle the controllers set at, you are more than welcome to.

I printed this file with one of the grips face-down, with supports for that side's voids, but I think it could also be printed with the large flat side down, if you trust your bed adhesion and bridging to make properly sized slots.

I printed with 2 walls, 20% cubic infill, and a 0.4mm nozzle out of Bambu PLA basic, but this isn't a high-stress or high-complexity part, so as long as it comes out dimension-accurate, you can definitely change those settings. 

The grey one in the photo is an older prototype, I changed the angle on the final model slightly because I found it more comfortable. The angle of the grip is a parameter in the fusion file, so you can download it and make it whatever you like.
