Smallrig 2987 to IKEA HEJNE

Well, this thing allows you to attach relatively cheap Smallrig 2987 directly to HEJNE. It has enough thickness to allow pressing on the release button.

You put two M6 hex-head bolts in it, then attach the adapter to 2987 via either supplied double ¼" bolts or four M4 inner-hex bolts, or both. Then just screw it to default HEJNE holes.
