Question: what has been your favorite thing to 3d print?

It’s a microchip that uses light to analyse cells. It can scan hundreds in just 100 seconds! And it cost only £10 to print.
We hope that one day it can be used to diagnose diseases in people, like a doctor shrank down onto a microchip.

I haven’t had time to print anything that’s not a microchip yet, but my co-workers keep asking me to print them a Christmas tree!
