Thanks in advance!

Sure thing. Start with a center line that will serve as an axis to revolve the roller around. Next, draw your edge lines on the left and right edges of the axis. Put a third in the center, higher than the first two. Draw two arcs connecting these outer lines to the center line. Let me know if this is confusing and I can upload a drawing for you.

They're quite solid as they stand, but I don't like leaving a wheel uncovered for any reason. For that reason I'll probably enclose the wheels, most likely in 1/8th aluminum sheet on which the bumpers will be mounted.
