All it would take is one piece of sharp debris to find its way in there.
Also, I'd be very concerned about the strength of a three spoke wheel, at least with the spoke profile and material you've chosen.

We plan on doing time trials to see how long it takes to replace a belt. We also plan on putting lexan shields over the access holes in the frame to prevent sharp debris from coming in contact with the belts. Also the wheel in the CAD is just a placeholder. The real wheels are made of UHMW that has been shelled out an only has one hole for access to tensioners.
