There is too many one push of the shampoo which I am using.
I made the spacer from which a stroke becomes half.
It's environment-friendly?

1.The value in 'HalfSpacer.scad' is corrected for resize.
2.It converts to 'stl' from 'scad'.
3.Printed!
4.A neck of bottle is attached with it.
5.Push, push, push...
