Made specifically for the creality nebula camera for the ender 3 v3Ke and the se with nebula smart kit. The mount Clips tightly on the rail and the base allows the camera to pivot in all four directions, the clip can be positioned low enough to get a good view of the nozzle. I printed mine with 3 walls and 20 percent infill. it needs no supports or anything special. It should work with most of the printable  ¼ camera screws found on here or the standard metal ones.
