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