DIY HDPE EXTRUDER
recycle your milk jugs and many more things into 3D printable filament
i've hacked a solder iron to make my heating source,
60W !!! way more powerfull than my first attempt
my auger is made of a 15 mm wood drill bit
i made about 3 meters of filament with 1.5 grinded bottles and many losses
the diameter goes from 2 to 4 mm
