But my question is, if we want to make our own instead of buying them,
do
we
need to get an STC?

Subject to confirmation, I believe there is a loophole in the FAR's that
let
the owner/operator of a certified aircraft make parts for that aircraft.
However, those parts must be installed by an A&P and suitable logbook
entries made.
