design an stp product

My name is wissam and i need to manufacture a toy made from rubber, i need the design file/stp file for it, i can give you photos and dimensions and descriptions of the product, its a rabbit which should be 12 cm height. i have another similar photos for a similar product in the shape of monkey, i need to design the rabbit somehow similar to the monkey but with some differences. ears needs to be shorter than in the photo, should not be sharp edged, should be connected together, and legs should be connected together and a bit straightened downward not flat to the front, arms should be similar to the ones in the monkey photo but should be thicker so that it does not break. color is orange, no dark orange, and the white colored parts are the inside of the ears and belly and tail. Eyes are blue and surrounded with white like in the rabbit photos. i also attached a giraffe photo, you can see that the right half circle of the giraffe has different texture/surface than the left half circle. this is how the arms of the rabbit needs to be, each arm to be different texture same as the giraffe arms/half circles/handles. please make sure the ears are thick connected to the head so that it does not break. thank you.
