In this study, a light weight portable manual food grinder for domestic use was designed and fabricated to meet food grinding needs that arise from erratic power supply in Nigeria. The design analysis for crank lever parameters and conveyor shaft diameter were done. To make the grinder light weight, the body of the machine, the front cover that house the grinding mechanisms and the support stand were printed with Fused deposition modelling 3D printer.The crank lever, conveyour shaft, grinding discs and the adjustment lever were made of cast alumimum metal. The design analysis revealed that an effort force of 600N on the crank lever will inflict maximum twisting moment of 72000 N-mm and 45000 Nmm on the conveyor shaft of the grinder. For the design of crank lever arm, the minimum boss diameter, boss length, boss thickness, lever thickness, lever width, and crank lever diameter were 18.24 mm, 22.9 mm, 3.42 mm, 8.58 mm, 17.36 mm and 14.94 mm respectively. The minimum conveyor shaft diameter was 25.02 mm while the machine required minimum power of 301.59W.
