Keep up the great work and please post your final version!

No, there's plenty of clearance for the hardware holding the rollers to the C channel. I'd really prefer to not take any more material out of the C, as the goal here was to go cheap and easy (hence going with aluminum from McMaster. If I go to something stronger (like a higher strength alloy), Then possibly I'd work on lowering the profile a bit.
I'd love to post the final version, but for me all designs are a work-in-progress. Maybe I'll post some renders side by side with a real thing if these actually get built? It's all really up to the team for what they'd like to build. I am just a mentor, anyway.
