This model is a Fidget Toy based on the principle of a Planetary Gearbox.
Model Data:
- Gear Module: 1.25mm
- Helical Angle: 45°
- Pressure Angle: 14.5°
- Total Gear Height: 20mm
- Number of teeth Ring Gear: 51
- Number of teeth Planet Gear: 18
If you want to print this model with your own print profile instead, here are the most important settings to save time:
- 3 walls for the Gears
- [0.55mm/0.65mm] [inner/outer] wall width for the planet gears
- [0.5mm/0.65mm] [inner/outer] wall width for the ring gear
You need to do this, because the slicer will otherwise place a lot of internal solid infill, which would take even more tome to print.
- 2 walls for "Base" and “Base Top”
- Concentric Top/Bottom for the Gears
- Monotonic Top/Bottom for “Base” and "Base Top"
Although “Archemedean Chords” infill saves a lot of time, I dont reccomend using it, because it makes the gears way less stable.
Asselmbly:
- Remove the pieces from the build Plate
- Put the Planet Gears inside the Ring Gear and space them approx. 120° from another. Be careful to orient them identically.
- Push in the Base/Planet Carrier from the top. Everithing should align itself.
- You can just pick up the whole Assembly and flip it around.
- Push the last part into the recesses. Depending on your Printers tolerances you may need to use a bit of glue or rotate it until it fits.
