Adapter for using a Viltrox L116T or an L132T LED photo light as an upgrade for an existing workbench lamp, inspired by an idea by Adam Savage, see https://www.youtube.com/watch?v=JL3uZ88vA_0. This bracket replaces parts of the bracket supplied with the photo lamp and allows the bracket to be clamped securely to an 11 mm round bolt on an existing workbench lighting fixture. This size is parametric, so for other diameters, just use the customizer.

The bracket may also fit other photo lights.

The hardware needed is four M3x20 countersunk screws, or longer, and four M4 nuts. '

For printing, I used auto-generated PrusaSlic3r supports, but I think you can also get acceptable results without it.
