I just had 3 big boxes of parts for the LaserWeb testing rig dropped off at my house by Canada Post courier service. These are the parts that were donated by @Mark_Carew_OpenBuild and the fine people at http://www.openbuilds.com under their FairShare give back program (Info on this program is available at http://openbuildspartstore.com/fairshare-program/). If you haven’t worked with v-slot rails, do yourself a favour and go to http://www.openbuilds.com to check out some of the cool builds people are doing, and stop in at http://openbuildspartstore.com/ to see the entire range of parts OpenBuilds uses.
