3D Printed Moon Phase Clock Steve Peterson 2024-02-28 | 3D printed pendulum clock with a large moon phase dial. This is one of my largest clocks with an accurate moon phase dial located at the front and center. It is as large as possible while still being printable on a Prusa MK3/4, Ender 3, or Bambu Lab P1S/A1. Runtime is 7.8 days with an accuracy of 1-2 minutes per week. The moon phase dial is accurate to within 1 day every 2.6 years.The STL files are available at the following links:myminifactory.com/object/3d-print-large-moon-phase-clock-362741printables.com/model/785631-large-moon-phase-clockThe clock follows the same easy to build design style as my other new clocks. The bill of materials has been reduced and the only machining required is cutting the arbors to length. The pendulum components drop into place without glue. The winding key is easier to build and more stable. Multiple size weight shells are provided to allow filling with either lead shot or BBs. The clock is 9" wide by 22" tall and 6.5" deep (225mm x 560mm x 165mm). The tip of the pendulum is 30" long (760mm). The minimum printer size is 210mm by 210mm. Total print time on a Prusa MK3S is around 160 hours using 1.7kg of PLA filament. Newer machines will reduce the print time considerably.A comprehensive 50 page assembly guide is included with the STL purchase, or you can download it from stevesclocks.com/sp14 if you want to see the steps ahead of time.

Clock Gear Optimizations for 3D Printing Steve Peterson 2023-11-25 | A description of the optimizations I make for better 3D printed clock gears. The first optimization is an extension of a concept called "Fancy Gears" that originated on a now defunct website called "Gary's Wooden Clocks". The premise is that clock gears only rotate in one direction, so only one surface of each gear tooth actually matters. The other surface can be any shape as long as it does not interfere with the other gear teeth. I make optimizations specifically to allow clean 3D printed gears without any unnecessary retractions. A second optimization was needed to allow for the way the Arachne slicing engine handles inside corners. The resulting gears only take around 60% as much time to print. Optimized gears print in 13 minutes compared to 22 minutes for the original gear.This is my newest clock with all of these gear optimizations. It is my most reliable weight driven clock.myminifactory.com/object/3d-print-small-8-day-clock-337387These clocks have the "Fancy Gear" optimization, which provides the biggest benefit. They were designed before the Arachne slicing engine was available, so they print best using the classic slicing algorithm.myminifactory.com/object/3d-print-32-day-clock-easy-build-156759myminifactory.com/object/3d-print-large-easy-build-clock-with-21-day-runtime-159691myminifactory.com/object/3d-print-medium-pendulum-wall-clock-142460myminifactory.com/object/3d-print-large-pendulum-wall-clock-137009Contents:0:00 Intro1:24 Original gear2:18 CAD optimization3:25 Fancy gear concept5:42 Optimized gear6:07 Arachne issues6:48 Arachne optimization 17:34 Arachne optimization 28:42 Optimized slicer view9:49 Summary11:26 0.6mm nozzle

Rev 2 Clock Updates Steve Peterson 2023-09-04 | Features from my latest clock have been added into five of my older designs. Three wall clocks added a solid connection between the pallet and pendulum plus adjustable height back standoffs. These edits are recommended to improve the pendulum efficiency. Existing clocks would see improved reliability by re-printing the pallet.The two easy-build wall clocks have an improved design to prevent gear 3 from pushing against the escapement. These edits extend upon the previous helical gear update and completely isolate gear 3 from the escapement. Existing clocks would be more reliable by re-printing the updated gear 3 and spacer 1.You can find the updates on MyMiniFactory in the area where you originally downloaded each design.

Coup Perdu Final Design Steve Peterson 2022-11-01 | The Coup Perdu clock is finished with many enhancements. The battery was added into the motor compartment and the clock can be either desktop or wall mounted.Coup Perdu is French for "lost beat" meaning the escapement moves only once during a complete back and forth motion of the pendulum. This allows the second hand to move 60 times per minute with a 1/2 second pendulum length.The clock rewinds every few minutes using a small N20 motor and two AA batteries. Estimates are a runtime of around 6 months.

Coup Perdu 3D Printed Prototype Steve Peterson 2022-10-03 | Prototype Coup Perdu escapement for a 3D printed desktop clock.Coup Perdu is French for "lost beat" meaning the escapement rotates one time during a complete back and forth motion of the pendulum. This allows the second hand to move 60 times per minute with a 1/2 second pendulum length.The design was optimized for 3D printing. The traditional metal pins were replaced with a flat printed escapement. This required the pallet arm with the lever arm to be moved to the other side of the escapement. Everything becomes much thinner and easier to print.A completed clock using this escapement is in progress.Contents: 0:00 Intro 0:53 Traditional Design 1:57 Drive Weights 2:40 Closeup 3:32 Super Closeup
Congreve clock prototype - 3D printed Steve Peterson 2022-08-04 | This is the prototype tray for a 3D printed Congreve style clock. The original design was developed in 1808 by Sir William Congreve. It is notoriously a poor timekeeper due to dust or other disturbances affecting the rate. This clock uses an Arduino Nano and an RC servo motor to tilt the tray. Adding a real time clock allows it to adjust the rate so the clock should be accurate to within a few seconds per year. It will still be quite noisy, so an enclosure might be needed to muffle the sound.The complete design should be available soon on MyMiniFactory at myminifactory.com/users/StevePetersonSubscribe to my channel to receive updates when new designs become available.
Sticky Clock Gear Solution Steve Peterson 2022-04-22 | Adding helical gears to my 3D printed Easy-Build clocks eliminates the "sticky gear" problem. The clocks can be found at MyMiniFactory: Large version: myminifactory.com/object/3d-print-159691 32-day version: myminifactory.com/object/3d-print-156759The original design allows the escapement to be pinched causing the clock to randomly stop every few days. Two gears were modified with a gentle helical angle to push away from the escapement. Reducing pressure against the escapement gives the clock more energy and reliability.Thanks go out to Felix for starting a discussion that eventually led to the solution.A wooden gear version of my stepper motor driven desk clock is introduced at the end of the video. This design may become available in the near future.Topics: 0:00 Intro 2:23 Problem Description 4:24 Gears in the Clock 5:50 Helical Gears 6:41 Adding New Gears 7:35 Fixed Clock 9:48 Future Developments 10:28 Wooden Desk Clock
Electromagnetic Pendulum Clock Steve Peterson 2021-12-16 | 3D printed electromagnetic pendulum clock. The electronics come from a cheap pendulum drive module purchased for under US$4. It should run for at least 6 months on two AA batteries. Everything was 3D printed on a Prusa MK3S. The overall size is around 11" (280mm) wide and 14" (355mm) tall. It requires a printer with at least a 225x195mm or 210x210mm print area. The design is getting prepared to be uploaded to MyMiniFactory. Check out some of my other designs at myminifactory.com/users/StevePeterson or my web site at stevesclocks.comSome of the inspiration comes from the pendulum drive mechanisms in Clayton Boyer's Toucan clock, HolzMechanik's Magica clock, and Dick Bipes electromagnetic pendulum clock. This clock has a ticking second hand. The electronics in this clock are significantly simpler since they are pulled from a standard pendulum drive module. There are no custom coils to wind. The only soldering required is to extend the battery terminals to span two AA batteries.The gear train is loosely based on my stepper motor desk clock at myminifactory.com/object/3d-print-silent-desk-clock-183452 The pendulum is sized so the second hand has a natural 60 ticks per minute. Accuracy should be tunable to around a minute per week.Steve

Stainless steel bushings with 1/16" music wire arbors2. Small printed holes with 1/16" music wire arbors3. Large printed holes with 1/8" music wire arborsStainless steel bushings are used in my first clock at myminifactory.com/object/3d-print-136608 They have low friction, but are a lot of additional effort.The small printed holes turned out to have nearly the same friction as the stainless steel bushings without the additional machining. They are used in my other clocks at myminifactory.com/object/3d-print-137009 and myminifactory.com/object/3d-print-142460Large diameter printed holes had larger friction, as expected. They might still be used in a few places where extra strength is required and the additional friction is allowable.
