[Challenge Solved] Weird assembly — I think this will be a hard one :)

Some light hints that may point you in the right direction:

Hint 1

The assembly is a part of a larger machine.

Hint 2

Several assemblies are meant to move side by side in unison.

Hint 3

The square-ish shaped piece is plastic that will wear down and be replaced.

Piano wire hammer/striker...can't remember the technical term.
- Hammer is the correct term, but that's not what they are. They come from a machine.
Almost looks like the inside of a piano key

Edit: just read the hints and it kinda fits
- Not for a piano. It's more industrial.
This has 3D printer adjacent vibes but I don't know if I can get closer than that.
- Interesting guess, but no.
Is that angled wear piece running in a track or does it ride on top of something and it's only constrained by the bar it's mounted to on the other end?

I feel like this is a piece of a machine used for manufacturing, but I have not a clue what it would do specifically lol
- Closest guess so far! The track is correct. Not for manufacturing per-say, but definitely a complex machine.
  
  Not for manufacturing per-say.... Does this wear piece that rides in a track press up on something? Are the tracks at varying depths? Is is a cam or perfectly round?
  
  Is it made of plastic or aluminum?
  
  I hate not knowing what it is lol
I don't know what the right word is, but some sort of cam follower? The left part slides along the cam, raising and lowering the lever and applying torque to the right attachment point. There could be multiple cams and levers on the same shaft.
- That's actually getting pretty close. The main difference is that the roles are reversed: The attachment point controls where the assembly goes.
  
  So some sort of latch? The attached mechanism pushes this thing to the left, where it ramps up over something, then falls down to hook into place? I can't imagine what would need several of these working side by side in unison though.
  
  Hmmm, no, the ramp is on the wrong side. Does it push something?
Brake caliper bracket, German.
- I'm afraid not. The only attachment point is the round hole on the right.
Oh MF i swear i saw something like this in my subaru service manual to keep the timing sprocket in place while you have the belt off.
- Lol. It's not car related. This is for a larger stationary machine.
Lifter assembly?
The right side clamps onto a bar and the left side rides on a cam and lifts the bar when the line passes under?
- Other comment guessed the same thing. The bar controls where the assembly goes instead.
Looks like a gear ratchet. Slope on the left piece allows a gear to rotate in one direction. Clamp on a bar on the right allows the assembly to be lifted to allow the gear to rotate in the other direction as well. Like a sort of gear brake?
- Not quite. The assembly moves around for other reasons.
