A printable adapter ring to improve the placement of the Puluz aftermarket lens guards for Ricoh Theta cameras on the Ricoh Theta X and make them removable.

If you own a dual-lens 360° camera, you know how easy it is to scratch the lenses and how much any scratch degrades the image, due to the short focal length of fisheye lenses.

And if you own a Ricoh Theta camera, you know the lenses regrettably aren’t replaceable.

Many Ricoh Theta owners install the Puluz lens guards for Ricoh Theta SC2, S or V onto their cameras to protect the camera’s lenses, although the lens guards tend to degrade the image a bit: if the lens guards get damaged, they only cost $25 to replace, which is much cheaper than the entire camera.

Unfortunately, the Puluz lens guards aren’t designed for the Theta X, and are too small to fit smartly on the larger lens bases of the X. They can be installed, but they don’t hold very well, and they sit too high, often creating blurry stitch lines.

With a little modification to the Puluz lens guards and a pair of this printable adapter ring, it’s possible to make the lens guards sit lower onto the Theta X’s lenses and hold onto he lens bases by friction alone, making them easily removable if you want to maximize image quality occasionally, without having to peel them off and glue them back on

The modified Puluz lens guards don’t sit a lot lower - maybe half a millimeter at the most - but it’s enough to improve the stitch line noticeably:
