I would expect since you are making a copy of a
exsisting product
you could have small production run made cheaply.
Its all in the tooling...
Even if the tooling were available cheap or free, a molder would still
charge a setup fee that might be tough to stomach. Once that is done,
and the machine tuned to make decent parts (typically machines and
molds need tweaking, or voids and warps will result), the parts are
really cheap. Might as well make 10000 of each.
PS. Looks at all the products around the house ...
Made in CHINA.
Not sure about this rant...
