High quality aluminum

Very sturdy and lightweight. Used them for a drone build and they held up well.

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.
