Design a product for 3d printing

hi i have design a product that i would like to be 3d printed, i sent the file as an stl but he showed me a picture and says its corrupt and will not work and help would be great for where i have gone wrong with my model. thanks in advance

pokemon viewer.skp (679.9 KB)

the version i am sharing is skp.

would it just be the card thats also in the image? as i dont want to keep sending the person files if they are not correct.

this is now resolved random image was issue

Yep. I’d also delete the image of the Pokemon card, as that will probably also mess up your Gcode.
