Double Pendulam

thingiverse

This is a double pendulum project. To assemble it, you will need to gather and prepare several components. The list of required parts includes two M4 nuts with 25mm length, eight M3 nuts measuring 15mm in diameter, eight M3 bolts, and two miniature ball bearings that measure 4x13x5mm each. You can purchase these bearings from Banggood at the following link: http://www.banggood.com/10pcs-4x13x5mm-Miniature-Metal-Sealed-Metric-Radial-Ball-Bearing-624-ZZ-p-79910.html. Five 8mm steel rods will also be necessary, which are then painted black for a clear visual contrast.
