Magnetic studio strobe light modifier and gel holder

thingiverse

I decided to create some simple and effective light modifiers for my studio lighting setup. These modifications will work seamlessly with any standard 7-inch reflector-equipped light. These use 0.125-inch strong magnets as the attachment mechanism, which are firmly pressed into the square holes around the outside rim of the modifier. I used a small pair of channel-lock style adjustable pliers to carefully squeeze them in, as the holes can be quite tight. gobo-mount.stl is the primary mounting part that securely clips onto the 7-inch strobe reflector and serves as the base for the rest of the parts to magnetically attach. It's recommended to use supports on this part during printing to ensure a successful overhang that attaches the mount to the reflector. gobo-frame.stl is the outer frame of the actual light modifier, which comes with a default thickness of 0.125 inches but can easily be scaled in the Z-axis to achieve any desired level of thickness or thinness. I typically print this part using two perimeters at a layer height of 0.25mm, 20% infill, and two top and bottom layers. This design can also be printed separately to create a simple magnetic gel holder. gobo-honeycomb.stl is the inner portion of the light modifier, modeled as a solid disk that requires separate printing (I use Simplify3D; refer to your slicer's documentation for more information). This is where the magic happens for these light modifiers. To achieve optimal results, set 0 top and bottom layers, one perimeter, honeycomb infill, and adjust the infill percentage to vary the size of the honeycomb pattern. Higher infill percentages will result in less spread on the light. It's essential to print this part at the same time as the frame so they bond together properly, ensuring both parts are aligned in the X and Y directions on the bed. This part can also be scaled in the Z-direction along with the frame to achieve any desired level of thickness or thinness. For a diffuser effect, you can scale this part down in the Z-axis to 2-3 layers thick and print it using a white/translucent filament while keeping the frame at its original thickness (to hold the magnets).
