This is the front with the fabric attached to the 3D printed part, to attach it I basically hand stitched the fabric on you can see the stitching, then I went over that with a 3D pen, to add filament around the stitching and to make it look more seamless, then I smoothed that out with a soldering iron. Also I added gesso on top of the grey print

This was the prototype

You can see I sewed the fabric there, then I stuffed it the sewed on top of the stuffing
