Secret Lab MAGNUS Pro magnetic headphone hook

Secret Labs offer a magnetic headphone hook for their desks, and its fairly cheap! However I didnt want to wait for the postage, and so I made my own. I started off with a headphone holder for the bose QC35s, and modified it to take some magnets, and attach to the magnet friendly bar that runs along the edge of the desk.

This is kind of a complicated model to print. Firstly, the model accepts two n52 60mm x 10mm x 3mm magnets. One of these magnets needs to be trapped within the print, and so you need to add in a pause to allow you addin this magnet. I have included a picture of where you need to add in the pause, but honestly your best bet is to just slice the model and have a look at it. The second magnet will lie in the slot above the other magnet. This one will need to be glued in after you have tested it. This magnet has a stronger bond because it will be flush with the desk. 

I tried a few different configurations for these magnets and this was by far the strongest. I had a few versions that worked mostly ok, but would fall off if you threw the headphones down a bit too fast. With this configuration, with the magnets mentioned above, the headphones absolutely cannot remove it from the desk, and all it takes some legit force to unlodge it.

Next, if you just enable supports, it will end up trapping supports in the inner magnet slot, but the model does need supports for the under side of the model, so I suggest you use support painting to ensure that you only get supports where you need them (I think normal supports did the job). I have included an image of what my sliced model looked like right before I sent it to the printer.

I tried to include my gcode for this, but printables say that it is invalid, so I included the 3mf file from bambu labs with all of my settings in there.

Other than these more complicated instructions, I printed mine at 0.02mm in PLA on a bambu labs P1P
