Thanks for the reply! That's actually not such a bad idea - ditching solid plastic for the "spider web" of support. It's kind of silly that I'd need to do that, but hey - whatever makes it cheaper, right?
Here's a photo of the "cheap" ($25) version. Three basic pieces. The base (big square), then the hexagonal piece on the right that fits into the base - you, the user, gets to determine the orientation that you insert it. Then the piece on top screws onto the piece on the right, allowing free rotation around the screw. The Megabrite LED module screws onto that top piece. Basically, that allows for total freedom of positioning the LED module; with those three pieces, you can achieve any direction you want across a whole hemisphere.
I could reduce the wall height of the hexagonal pieces but I'm afraid of it falling out, that's why I made them 1.5 cm tall. My best bet is reducing that base to the spider web spaghetti, don't you think? I'd reduce the size, but it's actually sized to screw onto a small PC fan which will keep the LED module cool while it's operating.
