The hole spacing on the bottom is about 18mm from center to center of the bottom holes, or: hole-9mm-hole-9mm-hole. approximately 24 mm apart. Ulanzi M-Rig has a hole spacing of about 16mm. It would be better if it was a standard size like 15mm with most SmallRig or sliding slots for multiple spacing to work. GoPro SmallRig Cage too. I'm confused. I'm trying to find a handy accessory to fill the gap, but I don't like paying for something that's unnecessary.
