No need for that! You've already established that any concerns with the current dustpan setup can solved by simply adding MORE DUSTPANS.

Great progress again, the end result looks like some really nice accurate work!

How much ground clearance do you have? If you're aiming for Robodojo, the floor is made of panels that don't always line up 100% prevent perfectly and the pit is usually dropped 20mm as an obstacle, so it's worth having 10-20mm clearance most of the way around to avoid getting snagged on something. Don't want to do a Cobalt!
