The Herb Typhoon - Weed grinder

This remix overhauls my previous model to now use standard 6mm Airsoft BB's, rather than the oddball sized bearing and spacers previously used. I also improved printability of the lower drawer chamber roof. The  bearing cages are also now split into 4 parts not 3. This project can still use the previous base if you've already printed it. 

Hardware: 

(5x each) M3x25 SHCS and M3 hex nuts. 

6mm airsoft BBs

Process: 

No sanding required other than top of drawer to fit however tight you want it. As-is its a tight fit, which I prefer. sand down the top edge of the back of the drawer if looser fitment is desired.
