First, thank you guys for sharing- it's appreciated.

My question for any/all- Are you currently or planning on printing bobbins and/or covers? If you
are, do you have tips about process, materials and printers?

i guess, if you mean building plastic bobbins, im on it. i´ve copied a p90 bobbin and the coverture,( shell, bodie...) and i´m pretty happy with it. im doing them in poliuretane. this is the process, more or less

poliuretane is a hard compound, easy to work with, and 2kg costs me 20€
there are also other resins as poliester, its harder but more fragile and epoxy that may be in between. and also you can give color to the ressins.
i wish this is an answer to your question.
