It says these are for 3D printing, but this is actually not the right kind for 3D printing. I didn't know better when I bought them. These are more for injection molding.

No complaints. Cap screws fit well, good tolerances.

The only beef I have with these parts is one end should have a portion of the diameter chamfered and slightly less in diameter to aid in guiding in the hole when doing the heated insertion.

A 3D-Printing enthusiast's best friend when it comes to assembling complex prints. I recently printed parts for a 4-cylinder short block. The inserts greatly simplified the assembly process of the main bearing caps and the rod bearing caps.
