I'm looking for some modules similar to these to upgrade my Victorion Combiner:

I want them in red, since I don't like the grey ones and the foot modules are too narrow to support Jumpstream and Dustup's weight properly.

Does anyone know of a website that sells generic Combiner modules that are similar to what is pictured above?
Ideally one that offers color choices, in case I want to buy the same part in a different color for another Combiner.



And please don't mention Shapeways, someone did contact me with some suitable parts, but then didn't enable the printing/sale option, so at the moment, that website isn't up for consideration.

I'm surprised the person who offered the parts suddenly ceased communication, given how helpful they'd been up to that point.
I'm hoping they eventually renew contact and activate the item for printing.
