I recently picked up the (excellent) @DiveGearExpress 6-degree light, for use as a primary on shorter dives. I made a version of my (mostly) 3D printed Goodman handle, only slightly modified from my XTAR D26 version. You can download the file for printing from Onshape here; at some point, I might get around to uploading a .3mf to Makerworld, but for now just right-click on the part --> Export --> as .3mf or .stl.
The only significant change from the D26 model is the retention system. Since there's no threaded hole (boo!), I made a sleeve that sits behind the light head, between the back cap and the wider part of the light head. With it in place and the back cap screwed on, the light can't come out of the holder. Note, I did have to remove the o-rings to slide the sleeve on.
As before, there's a printable plastic handle in the model, but I've found the plastic bottom handle a little too fragile. If you have access to a plasma CNC, you can cut the handle from 1/4" aluminum sheet and bend it very easily (I designed some printable dies to bend the handle precisely - if anyone wants, message me and I'll supply those).
