Pimax 5k/8k interface for narrow faces

thingiverse

This interface fits between the face cushion and the Pimax 5k+ or 8k to give a better fit for those with a narrow face and also reduce visual distortions (fishbowl look). Results are heavily dependent on face shape. Distortions were pretty bad for me on the stock Pimax 5k+, but I noticed that moving the bottom of the HMD out a few mm reduced them a lot. This adapter is thicker at the bottom for that reason and the sides are brought in to increase contact area, spreading out the pressure points to be more comfortable. If you find you have too much pressure on the cheeks, shorten the top strap a bit to transfer more weight to the forehead. **Installation (requires adhesive velcro strips):** FacePlate version1. Print only the top and bottom halves as oriented and glue them together. Printing the one piece interface could be done instead, but it takes longer and requires more clean up of support material. Attach some fuzzy velcro to the interface facing the Pimax and put rough velcro on the other side of the interface for the face pad to adhere to. Tip: 3 or 4 small strips is enough to secure it to the pimax - too much velcro and its hard to position without getting stuck in the wrong place. FacePlate version2. A thinner interface that gets your eyes closer to the lenses than version1. Which version to get depends on how deeply set your eyes are. Instead of a top and bottom there is a separate left and right side. FacePlate version3 (untested). a 5mm spacer, even thickness top and bottom without thickening the sides much (also left it thin in the nose area). For people that just need more eye relief. Should fit wide faces as well. Has cut-outs for glasses. FacePlate version4 -extra thick for glasses (untested). by request - like version1, but adds 10 mm overall to make room for glasses. Might not play well with the pimax lens distortion profile. **Notes:** It fits well with the Pimax face cushion, but the one from the Vive pro feels much cozier and there are 3rd party alternatives available like vrcover. The nose opening is reduced a bit, so that may be an issue for larger noses if you use the original Pimax face cushion. Changing the face cushion is also a way to help tune out fishbowl distortions. You may want to get a thinner or thicker face cushion to get your eyes closer or further from the lenses. This interface adds a couple mm (plus whatever velcro you use). The Pimax is VERY fussy about how your eyes are positioned relative to the lenses and they need to be the right distance away as well as perfectly centred. I highly recommend also doing the Vive Deluxe Audio Strap (DAS) mod as it makes it easier to consistently get the Pimax properly aligned and fitted and is more comfortable all around.
