Knob for captive nut
cults3d
This is yet another interchangeable screw / locking washer. By default, it features an integrated insert. Simply pause your print when the insert recess is almost complete (check in your Slicer preview at what depth it finishes) and install the insert. It should fit snugly as the filament will still be pliable. And then continue the print. You may encounter a bit of tangled filament probably, but the screw can straighten it out. The STL files are designed for a 1/4" bolt and the standard-sized nut that goes with it.
