Thermal inserts are a big thing when it comes to engineering with plastic. They make it easy to use threaded fasteners with plastic parts, and they work great with 3D printing too. There’s a bit of a knack to installing them without damaging your workpiece, however, and [John Culbertson] wanted to make using them as easy as possible. Thus, he created a thermal insert press of his very own!
If you’re not using heat-set inserts with your 3D printed parts you’re missing out. Hackaday’s own [Joshua Vasquez] wrote a great guide on thermal inserts which you heat up to securely melt the plastic as they are pushed into a slightly under-sized hole. While it’s possible to install these inserts by hand, using a press means much more consistent results.
