My flashforge creator pro is on its way (Woo!!!) Few more day's and I will be printing things finally. But my question is, say I have a object that I want to make bigger, at the moment I'm wanting to make this "painting" but bigger ( http://www.thingiverse.com/thing:472295) , say around 24in x 24 in. Currently I am using tinkercad to split up the pieces into the correct size, but its quite a process on there to just basically, cut out pieces from the stl.

Any easier way to go about cutting objects faster I guess is my question. Maybe I will give photoshop a shot with a 2D image, split the layers, then extrude them back to 3D.
