EWEE, The first 3D printed fully automatic herb grinder

Last crawled date: 4 years, 3 months ago

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

Mind to buy me a beer :)
What you need (easy variant without fans and leds):
About 15 bolts,1 nut and 2 washers but i forgot wich size they where
Please check with a caliper for correct bolt size.
