Emisar D4SV2 Flashlight to Gopro

If you want to fix a Emisar D4SV2 Flashlight to a Gopro mount this is your adapter.
I use it with a handlebar Gopro mount. The Flashlight clips in very tight. 

even bikepark is no problem.

(Osram W2 LED is best…)

Prusament PETG worked best for me. it has enough flex to click the light in.
