This low-cost, portable, and 3D-Printed Laboratory Equipment (3D-PLE) can be utilized to achieve the following learning outcomes: 

• Derive the equation of motion of a translational vibratory single degree of freedom system
• Setup the experimental system using Arduino, NI DAQ, and ADXL 335 accelerometer
• Obtain natural frequency both experimentally and theoretically
• Create Matlab Simulink model of the system and find the free-vibration response
• Compare the free-response both using the linearized equation and transfer function using Matlab
