3D Printing: Knurled brass inserts using a heat gun

In my current quest of building the Hypercube Evolution, one of the early and critical steps is putting in the knurled brass inserts into the 3D printed parts. These inserts are the receptacle for screws/bolts that would otherwise chew up the plastic you’ve printed. The standard instructions are to use a soldering iron but I wanted something with a little more accuracy so I used a heat gun. It works well so I thought I’d share a quick tutorial video I made!

In the end I’ve settled on 30-45 seconds as a proper amount of time for the heating. Otherwise I apologize for the hot mic. This was a one-take, direct from phone camera affair. If the tutorials get some traction I’ll up the production value, but for now it’ll do.
