PM me and I'll send you the files. I've tried making them public on Shapeways, but it wants me to open a store first.
just FYI - I didn't develop the market light holders design any further. The shape and design turned out good, but the material they were printed out of needed to be more flexible. Since I don't have a printer, doing trial and error to get materials that would work was not worth it, so I didn't take the design further.
