There are a few print bricks I've wanted that I'm surprised no one made before like:
1x2 print brick with it's own category
1x4 print brick with it's own category
1x4f print brick with it's own category
2x2 print brick with it's own category
Then there is some more complicated bricks like:
Flag brick prints that share with the 2x2f category
2x8 print bricks with their own category
1x6 or 1x8 print bricks with their own category
cone print bricks
umbrella shaped print bricks
sign shaped print bricks
roof shaped print bricks
Here's everything I want and more.

Flags.
Print Window decals. (yes someone made print windows but not many prints in existence).
Roofs
2x2f
1x4
2x2
4x4x4
etc
These are all the print ideas I could find at the moment. I'm still looking for computers, playing cards, food stuff, street signs, buisness signs, etc.
Anything lego for prints is basically what I want. I even have my own personal lego print pack which I could share but there is not many prints in it.
