two of my infance heroes now, will go to my desk on my work. if you like it, feel free to print it!!!! great souvenirs!!! SETTINGS FOR PRINT: you can use PLA, ABS or try it with flexible filament (i would love to see it printed with flexible fillament, it will be a great idea to be a "stress ball"). I recommend: Filament : PLA 1.75mm Height : 0.06mm Speed : 40mm/s Temperature : 210ºC (with fan always on) Infill : 10% (don't need more) Support : No Time to print: 4h Length: 2m After works : after printing it, just give it a bath with 99.9% acetone until surfaces are very smooth, wash it and work done!!!! Recomendation : the height of 0.06mm is very important because when it goes to the acetona bath, it will stay perfectly smooth!!! if you have any question, don't hesitate to ask, i will reply you as soon as possible. good printings!!!!
