Printed out without any issues. Great to use as a dummy CPU to give a sense of the size of one.

Despite having structural issues during the print due to the fact that I used pla, I was able to salvage the print by cutting off the misshapen parts. It works with syringe needles as advertised.

No issues with printing, I only had to cut some supports off in the end.

No issues with printing, all parts fit together nicely.

Fits perfectly on my Nikon lens. The support is a bit hard to remove but otherwise there are no problems.
