pimax 5k/8k psvr headstrap adapter

thingiverse

I wanted to create a pimax headstrap with more adjustment than the vive das, allowing me to use my own headphones. I took a broken psvr headstrap and created an adapter that has at least some adjustment on all axes. The whole headstrap can be moved up and down, slid in or out on the psvr slider, and tilted up and down on the hinge. The psvr headstrap rides a bit higher on the forehead than on the psvr, but it works fine still. It's nice to easily tweak the pimax hmd position for clarity and make it easier to pass the hmd to friends and family. This also relieves pressure from your face during longer play sessions. You'll be able to achieve a better fit with the vive das if you have a smaller head. I used drcube's excellent pimax top clip as a starting point and added a strong hinge to it. The hinge attaches to a plate that is secured to the psvr headstrap using the 4 screws from the donor psvr. The psvr slider locking lever goes into place to lock the slide. Finally, a cover angled similarly to the pimax hmd slides over the hinge to cover everything up. This cover is tight enough not to move in ABS, but if it does, you can drill a small hole on the underside through to the hinge and secure it with another screw from the donor psvr. Here are the parts you'll need: 1. A broken/donor psvr for the headstrap 2. A very small screwdriver 3. A small drill bit for the screw holes (I used both 0.9 mm and 1 mm, both worked fine) 4. A 5 mm drill bit to clean up the hinge hole (optional but makes things easier) 5. A small spring (I cut a small piece off of a biro pen) 6. An M5 bolt at least 45 mm long (I used 50 mm) with washers and optional spring washers (even better would be a thumb bolt or thumb nut for easier adjustment) I advise printing both parts of the hinge out of a tough plastic like ABS or PETG, as the hinge will be under some pressure from the bolt and take some stress from adjusting. I printed mine in ABS and it seems strong enough so far. The slide-on cover can be fine-printed in PLA if you prefer and secured with a screw on the underside. I have only printed this in ABS so far, so it may need a little adjustment for plastics with different characteristics. The slide-on cover will need supports in its current orientation, but you shouldn't need any support for the rest. Although I'm currently happy with my creation, I'm treating this as still a work in progress and may need to make future adjustments after more use.
