Printing Green Cheese for 100% Students

I've been giving awards for the best performance in First Year labs and exams. Last week I gave awards to the top five or so exam scores. When it came to the practical work I had a bit of a problem, what with ten students getting 100% in the work - which is awesome by the way folks. 

Anyhoo, it means that Una the 3D printer has been busy for a large chunk of today dropping out perfectly formed pieces of green cheese for next Monday's lecture....
