I made the scale plate of TQ with the acrylic board.
I was poor at processing of a plastic plate, and failed
repeatedly until now. It is distorted strangely
, also when dividing when cutting, or heating and bending .
But it was able to do well this time.
The thickness of an acrylic board called 3-mm
thickness thinks that it was good.
