Sure, send me the STL and that'll give me an idea of how much plastic there is. I can't see it being much over a tenner including shipping. If you fillet the corners and edges, that'll make it stronger without obstructing the area (assuming you have access to the original model). In terms of plastic, I have PLA, PETG, ABS and Nylon. Nylon is probably the strongest and best to deal with a wet environment whilst PLA can deform and degrade when in warm and wet environments. So make sure if you do go with the college they don't make it from PLA. Josh
