Treaded Insert Heat Press Soldering Iron Collet for Drill Press

I wanted to find a way to use an old drill press that has been hanging about the garage for years now as a threaded insert heat press for my 3D prints. I tried out @KristapsDravni_48462 https://www.printables.com/model/301925-heat-set-insert-press/files , but it was just a tad too big. Kristabs kindly put his Fusion 360 design up as well and that enabled me to see how he made the scallops around the edge to relieve the pressure when tightened into the drill press. So I did my drawing, which I suppose makes this a remix. So Thanks Kristabs.

Please excuse the state of my workstation in the photos.
