Lol . Are those decals ? or he had those eyes , customized ? <| sep |> Bitcoin will still be useful . <| sep |> PETG is really not that hard . The key things about it are accurate measurement and patience . Buy extra tubing , it ' s cheap . Take a couple of pieces and play with it and your bending tools . Make some bends , if they turn out badly toss that piece and make another . You ' re going to buy the bending tools anyway so the only thing you ' re out for practice is the cost of tubing . Worth every penny ! Alternatively , you can do PETG without ever bending it . Use angled fittings wherever the line needs to bend . It ' s quite a bit more expensive that way but it ' s easier and honestly I love the way it looks if it ' s done right . My next one will be done that way .
