The RHO-Lens for the Headplay is brilliant, but I thought that there would be a better to insert the lens & hold it. Each time I tried to install it, I would end up with finger marks on the lens.

So here is my answer to the problem, a lens holder that is held in position where the orginal headplay lens was.

On the four lens holder tabs is a piece of double sided tape to hold the lens in place, then the lens holder plate is screwed into place with four M2 x 6mm screws.

To get the lens in the correct position, insert the lens holder into the bottom half the Headplay first and then rest the RHO-Lens on the nose bridge and push down onto the double sided tape.
The RHO-Lens is from here: http://rho-lens.com/index.html

now for a newbie, how to rotate the file 180degrees .. ? I am taking this to the library nearby as they print 3d prints for quite cheap.. when I get there.. is it easy enough to figure out how to rotate the whole design ?

I've just rotated it for you and uploaded the new file.


Thanks so much!!!

Any special instructions I should relay to the third party printing company for best results? Infill, shell, material?

No, nothing special. Just rotate the stl file 180 degrees.


The company starts with a 20% infill and 1 shell. Is that adequate

20% infill ok, but the should be at less 2 if they are using a 0.4mm nozzle.


Hi All,

RHO-Lens have come up with a new design, which I have ordered because of the ability to have prescription lenses in them (I'm blind as a bat without my glasses).

Here is the link: https://www.indiegogo.com/projects/high-tech-optics-for-the-headplay-hd-fpv-goggle/x/8331478#/


Can anyone tell me what size screws are used with the plates to secure the lens to the lens holder?

I designed it for M2 screws (2mm).


Thx, appreciate the quick response.

Could you please reinforce the base of the legs please by putting a bridge between them. They breaking loose at the base when the print is almost done running the print job

Are you sure you have your printer setup correctly? I've printed a number of them and never had any problems with the 'legs' breaking loose (printed on 2 different printers)


It is setup write for sure.

Wow. This puts the lens exactly where I need it and holds it in place securely. No more worries about finding my lens loose and scratching the LCD. Thanks for sharing!

The Headplay are the best goggles I've ever laid hands on, and then I added the Rho Lens which made them better... until it fell out... and again... and again...

The problem is they are a tad big for hauling about, so when they get jostled the lens falls out. This solves that! Awesome work!

Happy that it works you.


I made this twice. Some quick notes:

This didn't work for with with supports off. Maybe this can be inverted so that the rectangular base is on the bottom instead of making the rectangular part on top and maybe it will be printable without supports?

It's a bit of a pain to remove all of the supports because the rectangle part is a little thin so it breaks easily. I printed this twice and both times I had a break in the rectangular base.

I haven't installed my RHO lens yet (it should be here next week).


It should be printed with the rectangle on the bottom, there is no need for support this way.


This design worked very well for me. No rafts or supports need, a really easy print. Holds the lens nicely and holds it at a perfect focal distance for me. Installation was easy and the lens is quite secure. Great job on this design... and thanks for sharing this here!

I made one of these last night. It is still sitting on the print bed. I ordered the RHO lens this past weekend so I can't try the brackets out until the RHOs arrive. Thanks for sharing these files.
