My wife came to me this morning and said:
"Hey, I've lost a lid for this bottle - can you make me a new one with your 3D printer please?"
I thought this was an excellent opportunity to show the value of the printer to her which would eventually allow me to buy a bigger, better one.
Test fitted on the 5, 15 and 30ml bottles. Not sure of longevity at this stage.
It took about 20 minutes to print.
