7/14 days pendulum clock with pointer disc

cults3d

Simple and functional, but reliable running pendulum clock with pointer disc and short pendulum. The clock is very suitable for those who do not mind 1-2 minutes reading error on the pointer disc. I was able to adjust my pendulum clock so that after 14 days of running, there was only 2-3 minutes deviation from standard time. The time can be set by simply turning the pointer disc. With the printer settings mentioned below, a print speed of 25 mm/s minimum and 35 mm/s maximum, and a fill density of 20% (cube), the total print time for me was 58 hours with a material consumption of 690 grams. The file "Gear_4mm" must be printed twice. In the video, these are the red and green gears after the pendulum wheel. The blue gear is the ""Gear_5mm" file. The pendulum rod consists of 3 parts that are plugged (hooked) together. The swing time of the pendulum can be adjusted with the nut on the pendulum (up - faster, down - slower). The assembly of the clock is shown in the video: https://www.youtube.com/watch?v=RfVWq-d1tQA Additional material: 1 x round D-3mm. L-100mm 1 x round D-3mm. L-55mm Optional for 14 days running time: 1 x round D-3mm L- 25mm 4 x universal screw D-4mm, L-35mm 1 x Universal screw D-3mm, L-20mm Optional for 14 days running time: 1 x universal screw D-3mm, L-20mm Optional for pendulum weight to screw: 6 x universal screw D-2mm, L-15mm 18 x washers M3 small (outer diameter approx. 7mm, thickness approx. 0.6mm) 15 x ball bearings: Outer diameter 10mm Shaft diameter 3mm Width 4mm E.g.: https://www.amazon.de/gp/product/B07VQVZKD8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Ball bearing covers must be removed. Ball bearings must be completely degreased and in the run very smoothly when dry. Ball bearings that run the smoothest and longest by hand should be installed in the pendulum wheel and pendulum. Then further forward, that is, toward the pointer disc, always take the better ball bearings so that the worst rotating ball bearing is installed in the "intermediate piece.stl" of the pointer disc. 2 ball bearings are needed for all the gears and the pendulum. Only the""intermediate piece.stl" has only one ball bearing. The position of the ball bearings can be seen. BBS balls: 1750 g for small weight - 7 days runtime - 1 bottle of BBS balls. 3500 g for heavy weight - 14 days run time. 2 bottles of BBS ball The 7 and 14 days refer to a drop height of the weight of 1.35 m.
