 there's a network-3D-printing company called mohou.com which i
previously investigated.

 QTY 2000 of the microdesktop corner parts.

 QTY 150 of each of the THIRTY FIVE laptop parts.

 uploading QTY 1 of the microdesktop corner part is 10 RMB per part
(so that would be 20,000 RMB or about $USD 3300).  putting them in a
batch of 60 and its 95 RMB per "part" (so that would be around $USD
500).

 it wouldn't be a large redesign (i hope) because as i am using a
parametric design in python it *should* be possible to just write an
alternative backend for pyopenscad that outputs STEP instead of
SCAD-which-gets-turned-into-STL.

 that's in theory.  in practice i really really don't want to spend
the time going down that route, even if there exists a STEP library
(in python).

 why STEP?  because that's the standard that injection molding uses,
because it's a geometric standard (not a triangles-and-faces standard
like STL).
