Galileo Pendulum Clock Mk II smaller, faster

thingiverse

This is a sleeker - and speedier - rendition of http://www.thingiverse.com/thing:1618843 and http://www.thingiverse.com/thing:1653916 The earlier version ticked once every second, this version ticks twice as fast. This version is crafted to be built on machines with a build volume of at least 130x130x120 (WxDxH) I plan one more version designed for a build volume of at least 120x120x100 Designed in Moment of Inspiration Made in PLA mostly on an Ultimaker Original plus some parts made on a CEL Robox and on a Flux3DP. A video of the finished project is here: https://youtu.be/A4zOAPIbeP0 Print Settings: Printer Brand: Ultimaker Printer: Ultimaker Original Rafts: No Supports: No Resolution: 0.2mm Infill: 20% to 40% Notes: Generally speaking, 1.2mm walls. Also generally, I used a brim. PLA only. Also used CEL Robox and Flux3DP Post-Printing: Holes sized with hand reamers. It is absolutely crucial that all moving parts move very freely. The pendulum bob and the hanging weight contain lead fishing sinkers. The weight of the bob and the hanging weight that work for me are (including the bottles) 43gm for the bob and 417gm for the hanging weight. By the way, the frame extensions can be stacked so you can print more and make a taller tower which will tick for longer. How I Designed This: Based on photos of a metal model of the Galileo pendulum. Designed in Moment of Inspiration and simulated in SimLab Composer.
