3D printed IPD adjusted lens cups for the Oculus Rift DK2

[Loworbit]

Hey there,
i've stumbled upon and just printed a pair of theese:

from Thingiverse http://www.thingiverse.com/thing:547091

I salvaged my B lens cups and the lenses fit very well in the printed parts. If you own a 3D printer give it a try, if your IPD doesn't match the 63.5mm of the Rift. Maybe you know someone with a 3D printer, ask him. If you're in Germany/Hamburg I'll make you a pair of lens cups for a beer

+1 rep OP
first thing first sorry for thread necro
I have an IPD of 71.3 and think i'd really benefit from these on my rift,
Is there anyone out there with a 3d printer who could print a set for me? for a fee ofc please PM if you could help.
Cheers fellow cmdrs.
PS. Im now streaming a bit in VR on twitch (I noticed no one streams VR thesedays) under the Name xPAINEx.

Thanks for Necro'ing, I missed this on the first go-round.
.
And thanks to the OP for posting, I may give this a try. I have abuddy who has a 3D printer and owes me a favor.

Wow, I missed this post too!
I've already ordered a set of the adjustment rings from vrgear (just shipped), but if they don't work out, I'll have to take a look at these. ...well, assuming I can find someone closer than germany to print them.

Thanks for the info!

BUMP with added info!
Found a site that is willing to print a set for just over £20 delivered.
http://uk-3d.com/
you need to use http://openjscad.org/ to convert the v.3 file from the 1st post in this thread to an .ssl file
which the site needs,
Not sure about changing the ipd of the base file,
but there is one thats set at 69.1 which should cover most users including myself,
also looking at the model theres not a great deal of room left to make it much wider and
I assume its 20mm high which would be the same height as the "A" cups.
Hope you wide eyed cmdrs like myself find this useful

Edit: theres a 15% discount too! use code Ultimaker15

suitable 3D print materials

I've been looking at various online 3d printing sites, and the shapeways one definitely seems to be the most economical.
Although there's other sites that offer some different materials that shapeways doesn't. Unfortunately at a significant price increase. From $50-$60, to well over $100 for these eyecups! (it's $22 at shapeways for the basic plastic)

The reason I'm asking is because someone had mentioned (can't find the post now) that the basic plastic material offered by shapeways is cheap, and can flake off, which ends up getting debris on the rift lenses or screen.

Just wondering what would be the most suitable material for printing these eyecups. Any 3d printing experts out there?

Quick update I gave the wrong site for the manual ipd adjustment go to
http://www.openscad.org/ with the base v3 file http://www.thingiverse.com/thing:547091/#files (3rd one down)
and do the following quoted from the guy who modded the original design,
"The model needs 2 parameters - IPD increase per eye = (your_ipd) minus 63.5) then divide by 2
lens cup height (as mesured from the mount plate to the top lens edge (not the lens center as it's not flat)
so it's 20mm for 'A' lens equivalent and 17mm for 'B' lens
or any other value from something around 9mm to infinity if you know the correct height for you eye sight.
As always go to http://www.vr-gear.com/ for the instructions on software modifications."

I have my .ssl file now going to use uk-3d.com to get them printed I'll let you know how i got on.

Definitely report back please would like to know more if these work. Thanks

Hey there,
Shapeways "strong an flexible" is the material to go. Although I have quite e few 3D printers in my cellar, I order printed models from Shapeways if I need especially sturdy parts or a better temperature stability. Strong and flexible is sls printed nylon and I noticed no "flaking of" or something like that. Some times Shapeways don't blew of all of the remaining nylon powder if you order a very complex model but with the IPD adjusted lens cups it should work just fine.

If some random guy prints this for you, 1€ for the plastic is to much already. 1 Kg pla costs around 16€ in germany...

That's good to hear, thanks for the info.
I already ordered a pair of the vr-gear adjustment rings from shapeways. Got the "strong&flexible - polished". They arrive tomorrow. Hoping they work well. My only concern now is the height of the eyecups with these on. I'm hoping they're 3mm thick, so I can simply use the 'B' cups, and be back to normal 'A' cup height.
If not, these fully printed cups are a nice fallback plan.

I have both types of IPD adjusters. Thought I would share my experience.

I initially bought the adjust rings that use your existing B cups and adjust them to a standard 69.5mm IPD and A height, bought these through Shapeways from http://www.vr-gear.com/
They work fine but have some downsides.
First off they are only available in set sizes, 59.5mm, 60.5mm, 66.5mm, 67.5mm, 68.5mm and 69.5mm. Thats great if your IPD is close to one of those sizes but mine is almost 71mm.
Secondly, they are not as good a fit inside the rift as the actual cups. I found that it was easy to "unscrew" the lens cup just by wiping clean the lens the wrong way. A couple of times this meant the lens fell out of the rift onto the floor, luckily no damage.
Lastly, the ones I had made by Shapeways are not great quality. I am not an expert on 3d printing but as I understand it if an insufficient temperature is used the material doesnt bond correctly resulting in a rough and almost hairy texture. This on its own would not be a problem but the rings shed particles into the rift every time I had to remove or replace them, this was a huge problem with annoying and hard to remove debris on the rift screen.

I ended up getting some of the cups printed as in the op. http://www.thingiverse.com/thing:547091
These are soooooo much better, it takes some fiddling to get the correct IPD sorted using various bits of software to adjust the file but has the benefit of fitting your IPD exactly.
I got mine printed through https://www.3dhubs.com/
This site allows you to print using someone local to you with a 3d printer, I had a great experience. The guy that printed mine did an extra set for free.
These fit much better, they dont shed and are much less fiddly than the rings to fit and remove.

I highly recommend the second ones.

Did you get the 'regular' ones or the polished ones? I got the impression that only the un-polished ones would be rough, and therefore subject to this debris issue.
Anyway, I guess I'll find out tomorrow how good these things are.

Give me the lowdown on the lense repalcement please. How did you secure your lenses in the new cup without any movement and correct depth.
Thank You

I like the actual cup idea do you have specs you sent? How did you secure your lenses? Thanks

Mine were the black ones, not polished.

As I recall you have to download the .scad file from thingiverse and import that into OpenSCAD (free). Then in there you have to set the IPD to your value and export it.

The lenses secure in the same way as the original lens cups. If you look inside your lens cups, underneath, there is a ring in there that secure the lens. Its pretty easy to use a small thin screwdriver (be REALLY careful) to pry this ring out. Once thats out the lens will fall out easy. The replacement printed cups come with a matching ring to secure the lens. Simples.
