I ordered a basic tripod for use with my PPM, and also found that I could not get the PPM to mount securely as the mount hole was too shallow. That would not be so bad except that it is on a section, as the pictures above show that protrude from the base of the projector.
I solved it by taking a round, self sticking, felt pad, designed to protect a wood floor from furniture, cut in in half, and stuck it to the tripod, leaving a gap in the middle so that the mounting “base” could recess in to it.
