This little mount helps attaching the Fantasea BlueRay Radiant dive torch (http://www.bhphotovideo.com/c/product/925620-REG/fantasea_line_6071_blueray_radiant_video_light.html) to the BCD.I made four different versions. First I thought i have to grab the lamp where the conical part begins so I made two variants for that area. After the print I realised maybe they will not work well because the big conical diameter difference. So I made a completely flat one which fits to the 28 mm thick flat part of the torch. Every design has a small, 0.7 mm verge on one of it's end to stick the mount to one of the torch 's carvings and to prevent slipping.After I printed the 28 mm flat version I discovered that the verge-less part of the lamp is not 28 mm thick completely - the diameter rises slightly on one end. So I made a fourth design also which considers this small uphill.I am not sure which version will be the best but I'll dive from next Sunday and all of them will be tested :)
