Summary

This is a new head for the sofirn mt-20 600lm diving lamp from dx.com.
I'm using it for underwater video recording toghether with a gopro3+. The light is now evenly distributed without the need of a diffusor.

Instructions

The goal was to machine it out of aluminium. But the cost were just too high for just two parts. This is why I printed it on my 3d printer out of HIPS. The screw needed some sanding to get it wo work smoothy. Underwater test not yet completed.

Here is the link to the diving lamp:

Just exchange the aluminium head with the printed part. You get a non focused light, perfect to iluminate those beautiful underwater creatures.
