Quick verdict
If your 3D printer build calls for M3 rectangular washer plates, this 10-piece metal set at USD 15.80 gives you a small, focused supply of silver-colored hardware. The rectangular profile is meant to hold frame components in consistent alignment, which matters when you're tightening brackets, belt retainers, or mounting plates during frame assembly. It is not a full hardware kit, but it can be a useful addition to a 3D printing maker hardware toolbox.
Who it suits
This set suits makers who need a modest number of M3 rectangular washers for a specific frame assembly task, especially when the build is described as compatible with V0 products. If you're replacing a few worn washers or adding extra support at key mounting points, a 10-pack gives you enough pieces for a single focused project. It is less suited to someone building an entire printer from scratch who expects a comprehensive fastener assortment.
What stands out from the listed details
The plates are described as durable metal in silver, with a rectangular washer shape. That shape can reduce unwanted movement compared to a round washer in some frame joints, which is useful when you want a retainer plate or belt retainer plate to stay put. The set includes 10 pieces, so you won't be buying a bulk box when you only need a handful.
The listed dimensions are compact: each plate is about 1.5 cm long, 0.5 cm wide, and 0.2 cm high. That gives you a sense of the footprint before you commit. The product is also described as a third-party accessory, which means it's not an official OEM part but should be evaluated on its own merits.
Meaningful trade-offs
The main trade-off is the quantity. Ten pieces is fine for a spot repair or a small assembly point, but if you're working across multiple printer frames or need washers at every bracket, you may need more than one pack. The compatibility note only mentions V0 products, so if you're working on a different frame design, you'll need to check whether the M3 size and rectangular profile suit your mounting points.
Because this is a third-party accessory, there is no manufacturer name attached to the listing. That's not a red flag by itself, but it means your assurance comes from the product description and your own fit check.
Product notes
10Pcs Durable Metal M3 Rectangular Washer Plates for 3D Printer Frame Assembly
The listing describes this 10-piece set as durable metal M3 rectangular washer plates, priced at USD 15.80. The silver finish and compact dimensions make them easy to handle while positioning frame parts. One reason to choose this set is the rectangular shape, which is designed to keep alignment stable during assembly. A limitation to keep in mind is the 10-piece count: it's likely enough for a targeted task, but not a full-frame hardware solution.
Bottom line
For someone working on a V0-compatible 3D printer frame assembly and needing a small set of M3 rectangular washers, this 10-piece metal pack is a straightforward buy at USD 15.80. Just be realistic about how many mounting points you need to cover, and confirm the fit for your specific frame before ordering.
