EWEE, The first 3D printed fully automatic herb grinder

thingiverse

This is the first fully automatic 3D printed herb grinder. It mixes all of your favorite herbs together and puts it into a prerolled cone. After use the machine will clean itself with 3 fans. If you want to build one yourself be aware, that it's a difficult project. For reference, it took me about a half a year to design, tweak and program it. Cones used for this machine: J ware Kingsize (30mmx109mm) Please note that this is not a easy project. You need to know how to read .ino files to change polarity of motors if turning the wrong way. Furthermore you do a lot of soldering. If this does not interrupt you go on and klick the i made one button More questions how the machine looks?
