Screws are terrible, ordinary screwdrivers don't work. These are self-tapping screws, so only a small amount of torque is required to turn them. Micro screwdrivers do not allow enough torque to be applied to be tightened enough to keep the part from slipping off. So I drilled holes for the screws and used bigger screws. Everything was fine until I took it off to adjust its position and broke it in half. A little epoxy and a little creativity boost and it all works great. I put felt pads on the magnet because the clicking is very loud. An aluminum one with mechanical hex bolts would be perfect and I'd happily pay more for a higher quality product. It looks like a 3D printed sphere with good intentions.
