Just a note: When we got our bot the plexiglass cable carrier that holds all the cords and dust hose was broken. We had a couple of vertical vinyl blinds (about 3.5" wide) left over from a project and they worked great. Reese just drilled a hole in each end of the plexi and holes to match in 3 layers of vinyl blinds; bolted them together; and it's been working great. No more stress on the plexi now. The vinyl is strong enough to hold up and yet very flexible.

Just thought it might work in a pinch for others who have had that thing break.

later,
