This is a 3d printable grinder/shredder intended for grinding plastic for extrusion into new spools of filament. All wh...ite pieces shown in the photo are printed out of Polycarbonate, while all the gray pieces were printed out of PLA. BE CAREFUL, you may have to modify the coupler to be able to grind more robust plastics.

Print times
All prints done at 150 mm/s
Box = 5.5 hours
Motor Mount = 5.5 hours
2 Shafts = 5 hours total
10 teeth = 5 hours total
Wing nut coupler = 1 hour
2 Bearings = 16 minutes total
2 Clamps = 6 hours total
Total Time = 28.25 hours
Assembly Instructions
After printing of all parts, test fit all teeth on shafts to make sure of proper fit.
Slide a bearing onto the shorter of the 2 shafts all the way toward the gear.
Insert one of the teeth into the opposite side of the box that you plan to insert the shaft through. This will make things easier when fitting the shaft through. This tooth will act as a bearing on the non gear side.
Insert another tooth into the side of the box that you are going to insert the first shaft through, but in the hole that shaft #2 will be in. This tooth will act as a bearing on the gear side.
Begin inserting the remaining 4 teeth for this shaft into the box from the top while feeding the first shaft through each individual tooth.
After the first shaft is in place, insert the second shaft into the other hole and begin inserting it through teeth just as with the other shaft.
Place the wing nut coupler on the drive shaft (shaft #2).
Insert the Windsheild Wiper motor into its circular housing with the screw outlet lined up within the slot provided.
Screw the wingnut onto the drive shaft of the motor.
Fix both the box and the motor housing to the desired work area or work bench using screws.
Connect the motor to the computer power supply.
