I saw this on 3ders.org [www.3ders.org]
I thought that it was a nice clear explanation of how to put brass inserts into prints. I would add though that it is worthwhile having a long brass screw in the insert so that it can be tweaked to be upright to the print.
Can I gently point out that I was linking to a URL that showed a technique that many people don't know about. I didn't say that it was anything new - I first used it at least 25 years ago on injection molded parts.
