VRProtect for HTC Vive

thingiverse

This is a quick and easy prescription lens adapter system for the HTC Vive that takes a standard set of lenses you can buy online cheaply from zenni.com. There's a frame piece that holds it in place with friction, and then a lens portion that snaps to the frame using magnets. This lets you easily change out the prescription or remove the lenses altogether for those who don't need them. The frame portion acts as a protective scaffolding above the lenses if you don't have one installed. If you want this printed for yourself, I've got it available on shapeways: https://www.shapeways.com/shops/pzdesigns You'll need both a lens and a frame piece printed out. Lenses can be obtained from a pair of prescription Zenni.com glasses, along with six magnets. Frame and Lens STL Files There are now two different versions of the STL available: 40mm and 43mm. All things being equal, I haven't really noticed any difference between them. If your inter-pupillary distance is on the high end, you may see some benefits from using the 43mm version. The glasses from Zenni are the same price, so it probably doesn't matter. 40mm Version The files that aren't marked with a size are the 40mm versions. You'll need to order these frames/lenses from Zenni.com: http://www.zennioptical.com/450021-metal-alloy-full-rim-frame-with-spring-hinge.html They should be approximately $20-26 US shipped. You can search around online to find coupon codes for free shipping or glare coating; I highly recommend the glare coating. 43mm Version These are exactly the same, except with larger lenses. Use these frames: http://www.zennioptical.com/550021-metal-alloy-full-rim-frame-with-spring-hinges.html The object files below have '43' in their name. Magnets You'll need to get six magnets to glue into the frame and lens pieces. The magnets needed are 1/8" diameter and 1/16" thick, model D21B-N52. You can buy them here: https://www.kjmagnetics.com/proddetail.asp?prod=D21B-N52 They're about $6 shipped. Installation To assemble the kit, first glue in the six magnets: three into the frame and three into the lens holder, so they'll attract each other. You can see a video here: https://youtu.be/Xb6jRee2Mpo To install the entire kit into the Vive, you need to expand the face piece to allow for maximum room. Insert the bottom of the kit into the bottom of the Vive and push down on the spring-loaded arms until you can slide the top pieces under the top of the Vive. Then you can contract the face piece of the Vive back down to hold it in place. Here's a video describing the process: https://youtu.be/nh7g7V6I4us Just for the sake of disclaimers, install and use these at your own risk. I'm not trying to get rich off this; just recoup some time spent and help fund my new printer. I spent a lot of time on development with this.
