Perfect for my 3D printer
These spacers fit perfectly on my frame. The anodizing looks great and prevents corrosion.

Great organization
The box they come in is compartmentalized which makes finding the right size easy.

Solid product
Threads are clean. One or two had minor scratches but nothing affecting performance.
