3x3孔板，雙側傾斜

Finally found a piece that lets me build sturdy right-angle joints without having to bend anything myself. The double-sided angled design locks in place perfectly with standard screws.

I was skeptical about metal construction parts feeling flimsy, but this 3x3 plate is surprisingly rigid and the angled edges fit snugly into my build. The dual-sided holes gave me way more connection options than I expected for such a small piece.

This angled plate's dual-sided holes made it a perfect fit for the joint I needed to reinforce, and the metal feels solid without any sharp edges. It clicked right into place with my other parts and held tight. Exactly what I needed for the build.
