AY 24/25 SEM 1: Week 1-2
This week, we started the process of designing our makeshift stepper motor slider. We planned to use M5 threaded rods and three 3D-printed cubes for this. Two cubes were initially printed, with one positioned at the top and the other at the bottom of our rod. A 3D printed bracket was also designed to be placed in between these two cubes and along the rod for pressing down onto the pipette buttons. The rod would then be attached to our motor using an M5 coupler, which is essentially a mechanical component used to connect two shafts, rods, or other rotating parts, and allowing them to transfer torque and rotational movement between them. The dimensions of the cubes were taken, with the top and bottom cubes sized at 42mm to accommodate the motor, while the distance of 2.5mm from the side of the pillar was designed to ensure proper alignment and function of the system. The distance between each hole was taken to be 5mm. While the printing is done, we plan on threading the holes of the cubes next week such that we can screw them onto our M5 threaded rods.
