This is an ergonomic grip for the New 3DS XL. There is nothing obstructing the headphone jack, power button, stylus, game cartridge slot, or charging port. I have rather large hands and I designed it to fit my specifications. I've also included a narrower version for people with normal sized hands. Please note that the top brackets snap into the little holes in the New 3DS XL, which I think are made for a wrist strap or something. In order to take the 3DS out of the ergonomic grip, one has to gently pry the top two tabs.
Instructions: Please see photos. The grips print in two halves. I included alignment pins which can be printed and placed into the alignment holes and aid in adhering the two halves. I recommend using an 80% infill with supports for the base piece (where the 3DS actually snaps in) for rigidity. The grips and alignment pins can be printed with 15% infill with no supports if you'd like. I also recommend printing on a smooth print sheet, rather than a textured one.
PS: If anyone wants the Rhino file, you'll have to go to thingiverse.com because printables doesn't support 3dm files for some reason. (https://www.thingiverse.com/thing:5412055)
