I have a FFCP clone.

It will only print up to 8.9" height x 5.7" width x 5.9" length
You are mixing up your X,Y and Z dimensions.

The FFCP has a print bed of 8.9" width (X-direction) by 5.7" deep (Y-direction) and can print up to a height of 5.9" (Z-direction).

Your object fits perfectly on your printbed with room to spare in all directions????
