Interesting idea from the UK’s Mindsets online. I haven’t found any pictures or video of the actual process or its products, so it may be one of those many brainstorms that turns out to be, ah, well…let’s just say “more interesting as an idea than in practice.” Still, I am intrigued. Feels like it could be a jumping-off point for some very clever small-shop process.

    I’ve done exactly this and gotten fairly good results. Avoid using the trigger and just push the glue in from the back in one smooth motion to get less bubbles.

  7. Not new, I was taught this technique to prototype silicon rubber buttons during my industrial design course. Drill or Mill an appropriate mold in plastic (or even wood?) and inject hot glue. 
    You can get very professional results, I’m surprised I don’t see more DIY devices using this.
