Sometimes I find it hard giving all the widgets and doohickeys meaningful names. I like Christmas foil decorations but this year I've been struggling to keep them hanging from the ceiling, they just keep pulling through the blu tack. Most things can be fixed with a laser cutter though, literally 90 seconds of drawing and cutting and I now have a handful of gadgets cut from 2mm perspex scrap. The string from the foil wraps through the gaps in the disk and the whole disk presses into the blu tack. In theory this should spread the weight load and stop them falling off the ceiling. It's working so far.
