Re-using past hardwear

[Hawiian Cadder]

from the rules i gleaned that if a team wants to use software from prior to the build season, they must make it accessible to all teams. if a team wants to pre fabricated hard-wear can we do the same thing? if we Post CAD files and a while paper to CD can we use a design that is identical or almost entirely gleaned off a prior robot?

the reason that i ask is that between 2006,2007,2008 and this year we have been refining a lift design, the new version is nearly identical to its prior versions.
