I wasn't really satisfied with any of the Raspi/camera mounts that I found online so I made this. Just two small parts, works with standard 1/4" LocLine, holds the printserver/camera wherever you want. Easy to reposition, holds steady, uses an existing hole, works great. The knob part works best when printed in ABS (PLA tends to drift), the X-shaped piece is fine in PLA. Hope you enjoy it, sorry for all the wires and clutter in the photos.
