Description
I wanted to give a try to the Goodman handle concept so I designed one to go with my new Sofirn SD01Pro dive light. Also, having a GoPro like camera I added a foldable arm to be able to jump into water with the light (and camera) hanging neatly on a D-ring. When the arm is fully folded out, the camera's field of view is more or less aligned with the center of the light beam.
The SD01's beam is quite narrow, so I also designed a diffuser to spread it a bit. The diffuser is very much a work in progress. The slots used to hold the diffuser are slim and the clamps tend to get easily damaged. But it is usable.
There are three sizes that fit my wife's and my hands. Of each size, there are variants for left or right hand and a version without a camera mount.
The handle is designed for two M5x25 stainless steel hex bolts and two M5 washers (OD at least 17mm). Another two M5x25 bolts are needed for the camera arm.
All holes for bolts need to be tapped.
I stretched a rubber sleeve over the end of the light where the camera touches the body when folded to protect the plastic of the camera enclosure. A strip of bicycle tire inner tube works nicely.
There are sharp edges on the inner side of the lanyard holes on the body of the light. Use a file to dull them before attaching the bolt snap!
PETG is advisable to help it survive summer days in a car. I used Fiberlogy PETG, because it seems to be a bit more flexible and less prone to cracking on impact than some other brands I have used. They also sell refills without a spool.
