Marek Senický, inventor of FilaMaker, a personal filament producing machine that grinds old plastic and make new filament for your 3D printer, has published a 3D printed compost shredder for kitchen on Thingiverse.

Kitchen waste shredder is a big helper in kitchen waste recycling. Marek's model is a small version of FilaMaker shredder and designed for shredding kitchen waste with safety. It can be applied for shredding organic waste such as vegetables, but not wood or bones or cooked meat.

The version 1 is a small shredder with up to 25Nm of torque. The version 2 shown in the video below uses ball bearings with 20 mm hole and can withstand up to 50Nm of torque. The latest version 3 uses ball bearings with 30mm hole and can stand up to 70 NM of torque.

According to Marek, the shredder has 33 3D printed parts and it took about 40 hours to print them out in PLA. In addition he also bought 23 standard size screws, 4 ball bearings and 2 square pipes for just €25. Almost a kilogram spool of PLA filament were used to print all the plastic parts. So the total cost was around €50~€60.

"I hope that this version can serve like a base for future models." Marek said. The stl files of the 3D printed Compost shredder version 3 were uploaded on Thingiverse. Check out the video below showing the the version 1 and version 2 in action.
