This is a Relativty compatible HMD design for hackers and researchers.
The physical IPD is adjustable within 57~87mm left and right independently.
A top rail mount option is also available.
Same as Relativty.
| Component | Qty |
|---|---|
| Fresnel lens(Diameter:42mm, Focal length:50mm)* | 2 |
| Strap | 1 |
| Face foam | 1 |
| 2 LCD panels with control board | 1 |
*Their Fresnel lenses are sold out, but you may find a similar lens in Aliexpress.
You also need to complete the build of the relativty motherboard when you want to use it with SteamVR or need 6DOF.
I optimized the 3D model for FDM (Fused Deposition Modeling) printers well.
Therefore, printing supports may not be required for this HMD model except for the face cover.
This HMD consists of three parts: HMD cover, and left and right eyeboxes.
The following table shows the list of 3D printed components (rows 1-3: HMD cover, rows 4-6: Eyebox).
| Model | Qty | Model | Qty | |
|---|---|---|---|---|
Top cover |
1 | Bottom cover |
1 | |
Face cover |
1 | L/R separator |
1 | |
Side strap holder |
2 | Top strap holder |
1 | |
Lens mounter |
2 | Eyebox pillar |
2 | |
Right display mounter |
1 | Left display mounter |
1 | |
Eyebox screw* |
2 |
*You can use general M6 screws instead of the 3D printed eyebox screw if you want.
I prepared a special top cover.
Please print ./stl/Top_rail.stl instead of ./stl/Top.stl.
The cross-section of the rail is as follows (unit:mm):
No special tools are required, but if you have hot glues, you can attach the form into the face cover easily.
Insert LCD panels into the display mounters at first.
The LCD panel is a fragile component, so do not put too much power.
If you bend the LCD mounter slightly, you can insert it without much power.
You already know why I wrote this caution, right?
After installing the LCD panels, I recommend assembly the LCD panel cables as follows:
The right-side cable should not be tightened with the center pole behind the LCD mounter.
The cable may collide with the motherboard if it is tightened.
Attach the L/R separator and the two eyeboxes into the bottom cover of the HMD using the eyebox screws or M6 screws.
And... I think you can build the HMD already because it is too simple.
If you want to verify the assembly, please check the CAD file in 3D-CAD, such as Fusion 360.
If the problem is related to the design of the HMD, please make an issue in this repository or report to @TenteEEEE.
If the problem seems to be related to software, please ask to Relativty team.
