The prompt
design a frame to fit a dc motor that has a gear attached to it, a small voltmeter lcd, and another gear. make sure the big black gear aligns perfectly with the small gear already attached to the DC motor and the distance between the hole for the lcd must not farther from 5cm so that the wires are to far from it SIZE: DC motor: lebar = 21,9 mm , aprox 22mm Panjang = 27,2 mm tinggi = 30,6 mm Panjang rod = 45,9 mm diameter rod = 2,2 mm gear diameter (with teeth) = 6,9 mm voltmeter display: Panjang = 22,6 mm lebar = 14,0 mm tinggi = 8,2 mm big black gear: teeth = 50 teeth (AI counted) tinggi tabung = 8 mm diameter lubang (bottom) = 4,3 mm diameter lubang (top) = 4,1 mm diameter gear = 41,6 mm tinggi gear = 1,1 mm
