I thought this went a bit differently. Shapeways used to have a 100% customer satisfaction guaranty. I don't know when they changed to what is apparently their 10 day return policy now. If he wasn't happy, Shapeways has always been happy to refund in the past. That apparently changed. The next time he contacted me, I went through parts I have laying around. I think he'll be happy with some of them. But again, the basic problem is mismatched parts were ordered originally. We will get it solved. Thanks. Al
