Easy Build Clock with a 32 Day Runtime
>> YOUR LINK HERE: ___ http://youtube.com/watch?v=djp73Q6tXZA
This is an easy to build 3D printed clock that has runtimes of up to 32 days. • The initial design goal was to simplify the bill of materials to make it easy to acquire the non-printed parts. These changes made the clock very efficient and it has 32 days of runtime using only 5kg of weight. Options for shorter runtimes would need much less weight. • The first design shown is available at https://www.myminifactory.com/object/... • The large version of the clock seen in the second half of the video is available at https://www.myminifactory.com/object/... The larger gear size take more energy so the runtime is limited to 21.5 days. • Assembly videos for both clocks should be available soon. • The complete bill of materials to build either clock is: • 0.85kg PLA for small clock, 1.2kg PLA for large clock • 25 6x3/4 wood screws • 18 3mm metal rod • 9 1.5mm or 1/16 metal rod • 12' fishing line • 5-10 lb. BBs or lead shot for the weight shell • 5 623RS (3x10x4mm) bearings • 4 springs from a ball point pen • 44 pennies for the pendulum bob • Related videos: • Assembly part 1, basic components • EZ Build Clock Assembly Part1 Components • Assembly part 2, final assembly • EZ Build Clock Assembly Part2 Adding ... • Debug steps • EZ Build Clock Debug Process • Steve
