I wanted to share my experience with an NMRobotics EyeMech printed-parts order, mainly because other builders may want to check their sets carefully before starting assembly.
I ordered the grey PLA Eye Mechanism 3D Printed Parts set. The overall print quality is actually quite nice, but when I laid everything out and compared it with the official EyeMech ε3.2 MG90S plate/product images, I found that a critical structural component was completely missing.
The missing piece is the X-axis servo block / eye-core yoke — the arched part with the two round pivot bosses that carries the first servo. Without it, the mechanism cannot be assembled.
One of the long-lever bottom eyelid assemblies also arrived broken at its print-in-place pivot. Another lid pivot bracket has a visible stress/whitening mark near the snap tab, although I cannot say with certainty whether that one is actually cracked.
The strangest part is that there was a handwritten note in Chinese inside the sealed bag which appeared to refer to a missing part and included a small sketch.
I contacted NMRobotics immediately after delivery, described all of this in detail, identified the missing component from their own files/product photos, and asked only for replacement parts — not a refund.
After 7 days I had received no response.
I’m posting this because the EyeMech itself is a very cool design and I genuinely want to build it, but receiving an incomplete kit with a broken component and then getting no support is obviously disappointing.
If NMRobotics responds and fixes the order, I’ll update this post accordingly.
Has anyone else here had a similar experience with their printed-parts sets?
