MAY 2018 UPDATE:
Unfortunately Shapeways have decided to discontinue metallic plastic along with other materials so I have added "professional plastic" in grey as alternative.
Underwater mount for three Kodak SP360 4k's with standard 3/8" thread. Specifically designed for minimum parallax and stitch lines whilst providing enough overlap under water. 6.5k final stitched resolution, compatible with standard SP360 underwater housing, requires three M5 (25mm) bolts which can be found on ebay, Amazon or in any hardware shop i.e. here
, alternatively you can cut off the wings from the thumbscrews that come with the underwater housing.
