Unofficial VR mount thread

AlexColgan 2014-12-24 00:46:01 UTC #1

Looking to try the latest VR apps for the Leap Motion Controller, but don't have a VR Developer Mount? Here are two DIY alternatives you can try in the meantime:

1. Duct tape. This is what we did before designing the mount. It gets a bit messy with tape residue after a while, but it works! When using tape, be sure that the device is securely mounted in the right place (see mount instructions here). Be sure not to block the positional tracking LEDs on the Oculus Rift; you might need to trim the tape to get it just right. Here's an example:

2. 3D print your own! We've made the CAD file for the mount available to the community; download it from Thingiverse or GrabCAD. A couple of important notes: When creating your mount, be sure to use high-resolution printing for the best results. You’ll need to use double-sided adhesive to attach the mount to your VR headset.

UPDATE!!! The new Universal VR Developer Mount can now be found here: http://www.thingiverse.com/thing:1589212

Attaching to the Oculus Rift CV1 or Vive? Right now the VR Developer Mount uses a thinner adhesive strip that sticks easily to flat HMDs like the Oculus Rift DK2. The mount also works on the Rift CV1 and Vive, though you'll want a slightly thicker foam adhesive than what's in the package right now. (It sticks, but since the mount is flat and the headsets are slightly curved, a thicker adhesive gives a nicer fit). We'll have updated mount kits soon. Anyone who has already ordered a mount and wants to use it on the Vive can get just about any 1/8" foam adhesive strips from their local hardware store, or get it online.

Why are we recommending alternatives? Our goal with the VR Developer Mount is to make it easy for you to experiment with VR using a consistent placement and angle. Whether you use the official mount, or a DIY alternative, we're happy as long as more developers can have access to VR tracking functionality.

Leap on the table with Oculus DK2

Update: We've just released a new unofficial CAD file designed to replace the standard cable door on the Oculus Rift DK2! The Leap Motion Cable Door Mount lets you easily attach and remove the Leap Motion Controller without the use of adhesive.

For best quality, we recommend printing in FDM PC-ABS material in .005" slices. You can download the file at Thingiverse or GrabCAD. Check it out:

wow I bought 2 Leap official mounts and realize that I can actually do it for free by 3d printing it myself.
Anyway, good job for leap motion team for sharing this cad file.

Well, 3D printing has its associated costs too -- but we like to give developers the option if they have access.

use the white plastic that comes with the original box

Ok, here is probably the cheapest mounting option available. I used 2 postal rubber bands that I had lying around. I'm not sure if they are of a standard size, but measured folded flat, the length (so half the circumference) is almost 17 cm. So in imperial sizes closest to 7 inch I guess.

I didn't know the STL for the official mount was out there so I ended up designing my own:) It doesn't use any glue and only blocks a couple of the Oculus' IR leds but it's kinda fragile. If anyone wants to try it out feel free do so. The STL files can be found at Thingiverse

Great idea with the The Leap Motion Cable Door Mount! I'll have to try it out

KevenZhou 2015-06-30 22:26:40 UTC #9

In the future Leap should enable multiple Leap Motion sensors to give the user a more realistic view, and maybe you would be able to mount Leap onto the walls around your house, and when you are wearing your VR box, you would be able to make your house look like a legendary house, or a scary house. These are all possible to do only if the Leap motion sensors could interact with each other in a very fast pace.

@KevenZhou --

This is definitely a common developer request and we've been experimenting with possible solutions for some time, however, we have not yet arrived upon a solution for release.

Speaking of DK2 cable door - this is what I have used through recent 3d Jam.

CadePeterson 2016-01-13 18:40:41 UTC #12

Wow, that's a robust little mount! Well done.

Hi Guys,

I tried to use this mount

(Picture shows original Mount from Thingiverse)

It is a Mount from Thingiverse which tilts the Leap round about 30°. I modified it a bit, so it fits to the DK2.

I chose this mount in the hope the tilt which it gives to the Leap will increase the detection in my application.

But it seems that the leap misinterprets the tilt. In desperation I tried a lot of things to get it fixed, like rotating the HeadControler and some scaling but nothing worked.

Because of the Post of Bertz which I think is showing a infinitely adjustable mount I was hoping anyone of you guys has a solution for this problem.

I know Leap is not meant to be tilted but I am positive that a tilted Leap has a positive effect my app.

(Unity 5.1, Core Asset 2.31, Oculus 0.5)

Bertz 2016-01-20 17:19:23 UTC #14

My mount definitely support tilting, but since I was aiming to people with official mount I've never tested it. Because hand positions are relative to the sensor, I think rotating hand controller should work. Make sure that placements of real and virtual controller are consistent. Also check coordinate conversions from controller to global space if you had them.

Tim_B 2016-01-22 08:20:02 UTC #15

Well it works for the human/non human hand models but not for the image hands. It positions the hand geometry correct with the Image Hands but it doesn´t map the texture/shader correct on it. I think it is because the Camera is still in the right angle (normal head mounted angle). But I can not rotate this as well, because then the player would always look down.
Do you have any solution for this?

No, there's no solution for this, as there's no good way to compensate for looking at a real-world object from a different angle. This was actually one of the considerations that led us to push forward on a 90-degree-facing mount.

alextoff 2016-02-28 00:02:00 UTC #18

I realize that mounting on the HMD may be the simplest solution, but for the sake of argument, is there any reason it can't be mounted around one's neck on a collar, or clipped onto the front of a shirt?

AlexColgan 2016-02-28 02:54:06 UTC #19

There are a few reasons. One is that our tracking is being relentlessly optimized for the head-mounted perspective. Another is that, when the controller is mounted on an HMD or sitting on a desktop, its physical movements can be known with a high degree of accuracy. On the desktop, it doesn't move at all. On the HMD, the position and orientation of the headset is always known. But on your collar or shirt, the position can shift around quite a bit. If the controller rotates a few degrees when you turn around, your virtual hands can drift several inches or more.

alextoff 2016-02-28 19:56:19 UTC #20

I see, thanks for the explanation. In that case I have a few ideas for a 3D printed mount with more attention to printability, but I'll have to wait on the headset before I work on it. In fact, I'm waiting on my Leap Motion as well, but I suppose I can take measurements from the already available printable mounts for that.
