Koss PortaPro adapter for Oculus Quest

thingiverse

This is a design I came up with for mounting headphones to the upcoming Oculus Quest. I've yet to test fit since I haven't received the quest yet. Thanks to Thingiverse user Jerware for the original design and Quest strap profile. I used the arms from his design and they're intended to work with the Koss PortaPro headphones. This model requires printing the socket piece with TPU and the rest can be PLA or PETG. The socket piece needs to be superglued to the bracket and the bracket is secured shut with an M2 screw. See pictures to get an idea of how it's assembled. If you don't print the socket with TPU (I used Shore hardness 95A) then the ball will not be able to be pressed in. These are designed to be rotated backward for storage. Only the ball piece needs supports and I printed with enough perimeters that there is no infill (something like 10 perimeters with a 0.4mm nozzle), otherwise it's not strong enough. I plan on making a few more ball pieces with different sizing for the arm holes as they're a bit loose and I'll upload when I get a chance. Feel free to ask questions in the comments if you need help with printing or assembly. Also feel free to modify this however you'd like! Edit 5/20/19, updated Quest_strap_bracket to version 2. Overall size increased to add strength and certain hard edges rounded. Socket.stl should be glued to the side with the larger hole and the head of an m2 screw should fit almost flush inside the exterior hole. I will update photos of this new design once I have it printed and glued. Edit 5/22/19, updated Quest_strap_bracket to version 3. Profile fits the Quest strap and snugs well with an M2 screw. I suggest "tapping" the hole first with an M2 and apply a little bit of heat to help form the threads. Thanks to Thingiverse user hypereven for testing the socket out with PLA instead of of TPU. Application of light heat to the socket allowed just enough flex to let the ball through. This is great news if you can't print with TPU!
