I recently got a SCI flex neck LED work light with a magnetic base but found that unless it was on a ferromagnetic surface, it was not stable and was not easy to use to illuminate close work on a work bench. To allow it to be used on a level nonmetallic surface, I design this stand using standard flat washer to attach the magnetic base to. It works really slick. I use PETG, but it will probably work OK in PLA as well. Print it on the flat side and use standard support for the washer recesses. I have found that Super Glue Fix-All Adhesive, that I get at Dollar Tree, works great for gluing in the washers and I use the magnet on the light to hold them in place while curing.
