This was modeled in two snap-together parts to allow for the insertion of an 8x2mm round magnet to hold the knob in place on the triangle.  It's designed to be more or less a friction fit, but there was some variability in the fit on all the panel locks on my laser, so I allowed the option to insert the magnet.  If they're not needed, snap the parts together and hit with a drop of thin CA if necessary.  If the magnet is needed, insert one into the depression on the knob body, then snap in the top piece.  I found I needed to add plate attached supports because of the indent on the top of the knob.  This added a negligible amount of print time and was easy to remove.
