There's a couple of places that might be of interest where you can get/do printed maps:-
Printed -
https://www.dxmaps.co.uk/product/great-circle-map-2/ - only 24 x 24 inches though.
Or
https://ns6t.net/azimuth/azimuth.html - this one you can download and will have to take somewhere to be printed for the larger sizes - 90cm x 128cm (~35 x 50 inches).
