HTC Vive Gun Stock (magnetic, adjustable, easy print)

thingiverse

<b>Updated on 8/8/2017</b> Added versions of <i>Controller - top</i> and <i>Controller - mount</i> modified to fit 45-degree twist magnets, as per request. I've included two versions: with and without the "stop bumps," since I don't have those magnets on hand to verify which feels better. Twist release magnets can be found at this link: http://catalog.polymagnet.com/1002305.html While there are many existing variants of gun stocks available for 3D printing or purchase (on Etsy, eBay, etc.), I had some issues with the few ones I tried, so I made my own version. <h4>Is it better? How is it different from other designs?</h4> There are a few things I'd like to point out: - This design is easier to print. It may not look as cool as a version made to resemble Picatinny rail, but the print time is significantly shorter, there's no need to remove tricky supports, and the construction is very sturdy. - Can be printed on small bed size - including <b>Monoprice Select Mini!</b> (which is what I use :) Just make sure you rotate the longest pieces [rail, stock a, stock b] and decrease the brim size to 6 lines). - The stock is adjustable. The spacing between controllers, as well as controllers and arm support can be adjusted in 1.6" - 2.4" increments to make sure it fits you comfortably. - The shoulder support part is lower than the rail, which makes sure it doesn't hit the headset during intense gaming sessions. - Multiple sizes of magnets are supported. If you have some, chances are they may fit. And if not, you can either buy the ones I used or <b>leave me a message with the exact dimensions of your magnets (diameter, height) and I'll make version for you :) </b> [absolute max would probably be around 20mm x 10mm]. - You can easily attach strap to have the accessory secured when not in use, or prevent it from falling when reloading in Onward while under fire. Just guide the strap through one of the unused holes in the rail. - And, well, my design is tried. I printed out a number of versions, improving parts in between, making sure the tolerances are correct and everything fits properly and stays strong. Some of the other available designs that I tried had issues with tolerances and wouldn't fit without manually trimming the parts after printing. But you be the judge, and please let me know if you have any feedback :). And most importantly, I hope you'll have fun using it! <h4>Parts to print:</h4> - 2 copies (one for each controller): <i>Controller - bottom</i> - 2 copies (one for each controller): <i>Controller - top</i> - select the variant for your magnet size - 2 copies (one for each controller): <i>Controller - mount</i> - select the variant for your magnet size <h4>Links to hardware (if you need to buy any):</h4> - screws: http://www.homedepot.com/p/Everbilt-8-32-Machine-Screw-Kit-800994/204331402 - nuts and washers: http://www.homedepot.com/p/Everbilt-94-Piece-Stainless-Steel-Nut-and-Washer-Kit-803334/205949033 - magnets: * http://www.homedepot.com/p/MASTER-MAGNETICS-0-7-in-Neodymium-Rare-Earth-Magnet-Discs-3-per-Pack-07047HD/202526369 * http://www.homedepot.com/p/MASTER-MAGNETICS-1-2-in-Neodymium-Rare-Earth-Magnet-Discs-6-per-Pack-07046HD/202526367?keyword=neodymium+6+per+pack If you head to Home Depot, you'll find a selection of magnets in the aisle with machine screws and fasteners: http://imgur.com/QZAhJz9 I recommend magnets: 0.472 x 0.118 inch (12 mm x 3 mm).
