I needed a light for my GoPro Hero 5 for low light. I designed this so I can mount it on my tripod. I wanted to be able to use both a battery and a wall outlet (AC-DC 12v). The Battery will last about 50 minutes of continues use. I used a 40mm 12v LED ring because I already had one on hand.
R1 ABS + PLA Model
I did two versions, one with supports and one without supports, both turned out good. Depends on how well your printer can bridge.
