$10.00Large Easy Build Clock with 21 Day Runtime

myminifactory

This is the largest version in my easy to build clock series.    A video of the clock and its smaller sibling can be seen at youtu.be/djp73Q6tXZA  This is the larger clock shown around halfway into the video.   Assembly videos are coming soon, The detailed assembly guide is located at https://www.patreon.com/posts/48476501 if you want to check it out before purchasing the design.   This is a great starter clock because of the simplified construction. Various options are provided with runtimes ranging from 4.6 days to 21.5 days. The longest runtime of 21.5 days is a bit aggressive, but the 14.3 day option is very stable. The shorter runtimes will be the most reliable and winding a clock every week or two is pretty impressive for a clock that you build yourself.    The list of non-printed components is half the size of my other designs. The complete bill of materials is:   ~1.2kg PLA filament in multiple colors   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   Total print time is around 100 hours. This design needs a printer with a bed size of at least 210x210x150mm. A Prusa MK3S, Creality Ender3, or other similarly sized machine will work great.    Multiple clock faces are included with simple numbers or roman numerals. Different hand styles and weight shell sizes are also included.   A smaller version of this clock is also available (https://www.myminifactory.com/object/3d-print-156759) with a 32 day runtime. The lighter weight gears need less energy so the runtime was increased. You have a choice between the larger more visually impressive clock or the smaller more technically impressive clock. Either one would look great on your wall.   Steve
