part of your tetra grabber 
Actually in general any really odd parts this year are going to be used for grabbing tetras because thats the only option other than drivetrain. I suppose there could be a couple other nifty ideas, but thats basicalyl all there is.
Looks like it’s for a three prong claw mechanism
The bottom one looks a little like a bearing holder, but probably isn’t. Anyhow it looks neat.
I think it is too small for a tetra holder (look at the size of the carpet and compare to the piece). It is probably part of a gear box assembly that has had a lot of material removed to conserve weight. (that’s my guess)
They’re just the claw joints, the larger piece is where the prongs are attatched. The smaller piece is attatched to a linear moving shaft which will allow the claws to open and close.
Looks like parts to a motor and bearing assembly. Maybe part of a sub-system for a lift or arm?
