Chiếc Nhẫn Lỗ (hiện vật 3D lịch sử)

This is a ring with diamond-shaped holes in it. Why is it special? Because it is the first ring we printed on the RepRap printer back in the day. It predates even the Mighty RepRap Power Ring. It was made to demonstrate that holes without support could be made ina cylindrical object.

Back then I only made PLA filament in natural clear, but now we have fancy materials like this eSun “Bismuth” PLA.
