Glad to help
If you find you need an extra layer of Opal Acrylic sheet because you can’t reach ADU target at lowest dim setting on Huion panel , these guys below do custom cut A3 and A2 pieces for reasonable prices.
Bunnings only sell the larger 600 x 900 pieces of opal acrylic ( I used Bunnings before I found out about these guys below )

Depending on your rig and set up , you may not need an extra layer of opal acrylic ??
