작가 설명
SP2: This is my largest and most impressive 3D printed wall clock. The escapement is up front and the gears are very visible. SP2B: Major update in Dec 2024 to be more reliable and easier to build is seen at https://youtu.be/16tLtGy5KAE A video of the original clock in operation can be found at https://youtu.be/kn1OaGAae5w The primary goals for this clock were to be accurate, functional, and nice looking. The deadbeat escapement is accurate to around 1-2 minutes per week. Runtime is nearly 8 days. Nearly every part has been optimized for 3D printing instead of just porting an old style brass design. The SP2B update is a complete refresh that is easier to assemble with a much smaller bill of materials. The gear tooth profile is a new style that prints cleaner and the escapement has been redesigned to give more consistent printed results. The clock is over 21 inches (0.55m) tall and 9 inches (0.23m) while fitting the print volume of a Prusa MK3S (210x250x210mm) or Creality Ender 3 (220x220x250mm). The pictures show the size of this clock next to my other much smaller clock design. Total print time is around 150 hours on a Prusa MK3 or 80 hours on a Prusa MK4. Total filament is around 1.5kg of PLA. A smaller version is also available that will fit a Prusa Mini (180x180x180mm) or similar sized machine. A few hidden non-printed parts are required to minimize friction and achieve the long runtime. They mainly consist of music wire for the arbors, bearings, common sized wood screws, fishing line, and filler for the weight shell.

Assembly videos of the original SP2 design are at: Part 1 - Subcomponent assembly https://youtu.be/NduVa_3wJFY Part 2 - Final assembly and testing https://youtu.be/IOmcpzH5iek Assembly videos for the updated SP2B design are coming soon. Steve Update 06-Oct-20 Added gear8_shaft.stl to replace the 5/16" brass fabricated metal part if desired. The printed part appears strong enough if printed with 10 perimeters, although the metal part is preferred. Update 15-Oct-20 Replaced back_frame_upper_met.stl and front_frame_upper.stl with newer versions. The previous versions accidentally had 8mm diameter pendulum support bearings, but experiments showed that 10mm diameter bearings have lower friction. The assembly notes correctly list the 10mm sizes. This only applies if building the metric version of the clock. There are no changes for the imperial version. Update 19-Oct-20 Refreshed back_frame_lower_imp.stl and back_frame_lower_met.stl with modified versions. The old versions had a small gap in one of the support posts that created a weak spot. It is one solid object now

See the assembly notes for full details. Most parts print with PLA, 0.15-0.20mm layer heights, and 4 perimeters.
