Pendule double - double pendulum

thingiverse

Here's a double pendulum made from an old hand spinner. I used two bearings that were salvaged from the spinner to create this unique piece. The "pebble" is printed in phosphorescent filament, which gives it a really cool effect when it's dark outside. You can place it on any metal surface and watch as it swings back and forth, mesmerizing anyone who sees it. To make sure my double pendulum stays put, I attached three strong magnets to the base of the support. This allows me to stick it onto refrigerators, radiators, or any other metal object that's nearby. It's a great way to add some visual interest to your home decor!
