SecKit Sk-Go 9-point leveling side mount

thingiverse

People often create simple mounts that fit an M3 hammer nut or drop in t-nut right into the center and then screw onto the bed frame using an M4x12mm bolt. This setup creates a mount where one didn't exist before, eliminating the need for a weird little bracket. You will likely require a 40ish-mm flat head M3 for the actual bed bolt. This point can be adjusted from the top, unlike other points.
