I kept heat pressing my inserts at an angle so I looked for a solution, but none of them fit the equipment I had. This collar will attach a Pinecil soldering iron or any other one with a similar shape to a drill press or drill guide. I have included files for a 42.75mm chuck and a 53mm chuck. The 42mm one is the size of the Woodpeckers Auto Angle Drill Guide, it is a standard size 1/2" chuck. The 53mm chuck is on a Craftsman drill press, but that is pretty standard as well. If your drill press has a different size chuck let me know and I can adjust the files. You will need 4 M3 x 12mm bolts and 4 M3 nuts to clamp it tight. Happy Printing!
