Cheap Acrylic Off Cuts for CNC Milling & Engraving Practice

I've posted this video as a follow up to a post I made on my website www.m6mdr.co.uk/cheap-acrylic-...
I recently ordered a box of assorted acrylic off cuts for practicing with on my CNC Milling and Engraving machine and this is what I got.
This is a 4Kg box of assorted colours and sizes which cost £17 delivered from eBay. I'm more than impressed and have plenty to keep me busy for a good while.
