Heat Set Insert Tool Holder

This model was just what I was looking for, but I found that my insert tools needed different hole sizes. Rather than bother the designer for a remix, I created a replica in Fusion 360 so I could test various hole sizes and clearances. With hole sizes sorted, I looked for some way of securing the insert tools in the holder, knowing how easy it would be to knock the holder over and scatter the insert tools everywhere. Since the adapter on my soldering iron is 4mm, I added countersunk holes to the bottom of the holder to allow 4mm screws to penetrate through to the holes on the top, which the bits then screw on to. My screws penetrated too far into the upper hole, so I increased the height of the holder to expose just enough thread to capture the bits without making it a pain to unscrew them when needed. The 4mm screws self-thread into the holder. The countersunk holes are tapered at 45 degrees to avoid supports.I included the F360 file, which has user parameters to enable flexibility in
