Hmmm … nice rendering skills! 
For the coffee sorter project, this is too early though … we’d want to go through at least two product releases with a simple, box-shaped machine before adding any design that deserves a rendering.
(This is a machine for farmers in outback Nepal, India, Ethiopia etc. … I don’t expect them to attach much value to the form when this machine is the only one worldwide to relieve them of manual sorting …)
However, have a look at the Bitcut “open source furniture” project by @m_tantawy and team. You can read more about it and offer to help with renderings in this topic. Hope you like that project, too!
