![]() ![]() Update 15-Oct-20 Replaced back_frame_upper_met.stl and front_frame_upper.stl with newer versions. The printed part appears strong enough if printed with 10 perimeters, although the metal part is preferred. ![]() Update 06-Oct-20 Added gear8_shaft.stl to replace the 5/16" brass fabricated metal part if desired. They are still available for download as individual files by scrolling below the main description and expanding the "Object Parts" section. Note regarding updated files: STL files that get updated after the initial release do not always get added to the ZIP file. Use the forum at to discuss clock making topics or assembly issues. Go to to download the latest assembly guide. They mainly consist of music wire for the arbors, bearings, common sized wood screws, fishing line, and filler for the weight shell. The design includes both metric and imperial sized components to support parts available in your country. Total print time is 150 hours using 1.3kg of PLA filament. A future scaled version is planned that will fit a Prusa Mini (180x180x180mm) or similar sized machine.Ī few hidden non-printed parts are required to minimize friction and achieve the long runtime. The pictures show the size of this clock next to my other much smaller clock design. The clock is nearly 20 inches (0.5m) tall while fitting the print volume of a Prusa MK3S (210x250x210mm) or Creality Ender 3 (220x220x250mm). The gear tooth profile is a new style that prints cleaner and the escapement has been redesigned to give more consistent printed results. ![]() Nearly every part has been optimized for 3D printing instead of just porting an old style brass design. Runtime is more than 4 days and I think it has a nice symmetrical look. The deadbeat escapement is accurate to around 1-2 minutes per week. The primary goals for this clock were to be accurate, functional, and nice looking. The escapement is up front and the gears are very visible.Ī video of the clock in operation can be found at This is my largest and most impressive 3D printed wall clock. ![]()
