Adjustable focal length VR Goggles. Occulus "Thrift".
- 25mm Perspex lenses (Cardboard V1).
- 2 x 3mm bolts
- Hot Glue
Simply print the goggles and adjust the hood using 2 x 3mm bolts to friction fit the hood to the desired focal length.
Use hot glue to spot attach the lenses to the faceplate.

- Updated the faceplate and mask to have a higher nose bridge to avoid pinching
If you've got bridging setup correctly you should be able to print the mask without requiring any supports. The one pictured here had no supports.
Some filing may be necessary to get the face plate to fit inside the mask, the tolerances are pretty tight but makes a very nice firm fit with a little bit of filing.
Currently the lenses are hot glued to the opposite side of the face mask. I need to adjust the faceplate to accept different sized lenses.
You may also want to put a bead of hot glue down across the front of the mask and hood in order to stop any scratching of your phone surface. The dried hot glue makes a nice rubbery texture which should stop any movement and also provide a barrier to scratching your phone.
