Picade Artwork Templates

I have a newer 10" Picade (Pico8 model, not sure if it’s the same as the 2019 model) and have been looking all over for the Artwork Templates so I can create some art.

I have found almost everything I needed here: https://github.com/pimoroni/picade/blob/master/picade-docs/picade-artwork-templates-a4-2021.pdf

The side panels template is either missing or does not exist. Does anyone happen to have this as a PSD, and / or know what the best paper size to use per side is? IE: One side will fit on an 8.5x11 or 11x17 sheet.

Thank you if you can help, I am also going to ask in the Artwork thread I saw here.
