I would be interested to know what this part would cost to manufacture, either machined or cast.

Initial quantity of 15 required, which could be bumped to 30 if this would drop the per part cost.

It is effectively a 20mm diameter cylinder with 30mm cylinders at each end, slightly offset in opposite directions. Overall length is 140mm.

As an alternative to machining, if anyone can do lost PLA casting, I can 3D print masters for use with the process.

The part was drawn in Fusion 360, so can presumably share the drawing if needed.
