Magnifier Lamp Desk Swivel Mount

A mount I made to mount a magnifying lamp on my desk.  The clamp that came with the lamp wasn't gripping enough.  I made this that I could bolt/screw onto the desk.  No supports needed.  I used PLA but PETG is probably better for this application.  I don't remember the settings I used to print this, but considering the force that is on it, I would use at least 3mm perimeters (top, bottom, and sides).  Infill maybe at least 25%.  Otoh, I might have printed it with 100% infill.  It was a few years ago.  It's been holding up great.  No problems at all.
