First of all a very big thank you to Matt Ball, PM Models UK on YouTube, go and watch. He printed the parts out for me saving me time and money

Material used for the Vacform canopy: PETG clear 0.5 mm A5 sheets.
Vacform machine can be found on eBay under Dental Vacuum Forming Machine.
Software used for creating the 3D CAD models: Plasticity 1.4.20.

There are some great Plasticity tutorials on YouTube, LEAD (Learn Everything About Design) and Nikita Kapustin just a few to mention.
These ones I found easier to watch and went at a pace I could follow.
