If you have cabinet with inner doors you may find that hinges try to move the doors inwards, so you need something to stop/limit it. This small stopper is fixed with small furniture/wood screw 3x16mm (screw head must be 6mm or smaller in diameter). There is “left” and “right” version - it only matters to which side you want to screw it (top/bottom or side wall).

The top surface has 8mm circle to place silicone bumper/dempfer, if you won't that circle don't print in full (e.g. cut top 1mm in slicer).

I printed it in 0.1mm height layer since it's a small tiny thing.
