Photo-Umbrella fastener for light-stand

thingiverse

When photographing on a budget, your inexpensive digicam may lack sufficient lighting at times. A simple solution is attaching a reflection-umbrella to a high-powered lamp from a nearby home improvement store. However, be cautious as these lamps have an artificial light color temperature that should not be mixed with natural light. To fasten the umbrella, you'll need an M4 grub-screw (or screw).
