You could put a post on here (and maybe the Ric forum?), explain there's a lead time and see? Worth doing a design registration if you're serious about it though. Any idea what it's likely to cost?
I sold my Ric 'cause I couldn't get on with exactly this issue and in those day additive manufacturing hadn't been invented. Actually not strictly true it was was called rapid prototyping then and still very costly for hobbyists.
