We were looking for an excuse to investigate 3D printing, so when our neighbour got into the business of printing ear protectors for frontline staff with proceeds going to the food bank AND had more orders than he could fill it seemed like the perfect excuse.
We printed a few hundred ear protectors until the neighbour got caught up and then Brendan started experimenting with other things. I wrote about the race cars we made but he's had much too much fun playing.
