I've been looking for a good service where I can upload my model and I always see Shapeways as the most recommended. However when I upload my model it regularly prices it 3/4x as much for the versatile plastic https://trackeasy.fun/usps/ https://showbox.tools/ http://essaywriter.fun/ as you get for pla from a service like 3dhubs. Also I notice with both that the price changes for the exact same model depending on what order I click the buttons. Is this normal. What should I do to get a good balance of decent printing and cheap price?
