Nintendo Switch VR Adaptor (Customizable)
Description
As you already noticed from the title, this is another attempt to mount a Nintendo Switch onto your head, but in a professional looking way without wasting a ton of money. The total costs for this headset project is below 5 euro and this includes printing and plastic cost. Yes! You don´t even need the original Nintendo Labo VR set for this to be useful. In fact you don´t even need any game for this. Just download the Youtube App and search for "3D" and/or "SBS". SBS stands for "Side by Side". If you watch those videos with a normal player it looks like you see the same image twice. One on the left and the one on the right. Those are the images used for each eye. All these goggles are doing is splitting the image in between, so each eye only sees one image and you get a 3D view. Games with LABO-VR support (beside LABO itself of course) are "Mario Odyssee", "Zelda", "Captain Toad - Treasure Tracker". There are also some third party games supporting this."Spice and Wolf VR", "Thumper" and probably more. I used the "VR Box" headset, which gets sold on Pound-Stores (1 Euro Shop, Dollar stores) and only costs about 1-3 Euro. I actually cannot remember the real pricing, but it for sure was less then three euro. I got it from a Netherlands shop chain called "Action" here in Germany. https://www.action.com/de-de/p/virtual-reality-brille/ All that is required is to remove everything from the front of the VR Box, which usually takes a mobile phone as device of choice. However the universal adapter used is not universal enough, as the switch does not fit. So unplug and unscrew everything. It is a good idea to remove the rubber head band for the time being, so it cannot get damaged or take glue while dangling around. You will notice that on one side there is a cooling grid uprising from the goggles. This needs to be trimmed off, as we need the space to fit the Nintendo Switch centred. Don´t worry, the console will get its cooling from the back and top, as the mount has matching openings for the air vents. The clippers, delivered with next to all 3d printers these days, will do fine. The plastic is very DIY friendly. It does not split or crack. It just breaks where it gets actively cut. Once done get a sheet of sand paper and rub the entire thing over a few times to get it more or less even and smooth. It is not possible to get is straight all the way, but that is not recommended as the top head strap mount is quite next to the edge and would get weakened. Just take a look onto the images to see how mine looks. The edge will mostly covered by the new adapter, so it does not matter anyway. Give the 3d printed adapter a good clean and remove any loose 3d print hairs. It is also a good idea to sand the inside of the Switch mount to prevent the switch from getting scratched by leftover support pillars. I designed the adapter to fit my switch, which has a protective glass cover and a metal plate on the back for magnetic mounting a cover/stand. In total it is just about 0.8 mm. The metal plate is the reason why you can´t see on the back of my Nintendo Switch on the photos. If you switch feels loose, then change the thickness using FreeCAD or just tape some foam into the adapter. The VR Box comes with pads that may fit your need here. Even if my model provided screw holes and additional holes to fit the screwdriver through, I do not recommend using them. The pillars the screws were originally drilled in are most likely already split at the top due to the weak plastic. You don´t want your trusty Nintendo Switch´s live rely on that crap. Make sure the adapter is the right way up and glue it in. The single hole in the switch mount is for the USB. That´s the bottom side and must be on the same side as the nose pocket of your goggles. The two long slots are power and volume buttons, head phone and vent openings. I used plastic instant glue on the pillars and the holes in the adapter. You may use hot glue, but I recommend a real glue. The headset is so cheap, so If something will break or you want to try a new revision, just buy a new one. Don´t risk your Nintendo Switch without a proper reason. I added the FreeCAD V0.19 source file, so anyone can adapt the mount without any hassle. Make sure you don´t use a FreeCAD version lower than 0.19 or the file may break during edit or loading. This project may get an update or two in the future, until I am totally pleased with it. That´s why I marked it as in progress.
