What is Galileo?

Galileo is a collection of planetary gearbox designs by JaredC01 from the Voron Design team.

Galileo2 G2E is a 3D printer filament extruder system designed for the Voron Stealthburner toolhead.

Galileo2 (G2E) Stealthburner Clockwork2 Module

The Galileo 2 Extruder (G2E) is designed as a drop-in replacement for Voron printers utilizing the Stealthburner toolhead. G2E features a custom large drive gear (16mm diameter) mated to an idler bearing to help prevent extruder artifacting due to gear meshing, and because it features a planetary gearbox, there’s no issue with gear meshing vibrations/noise found with improperly adjusted CW2 extruders.

Galileo2 G2E Extruder vs Galileo1:

• A full redesign, moving to a 9:1 gear ratio and optimizing the gearbox design over Galileo 1. No parts from Galileo 1 are reused with Galileo 2.
• Custom 9T stepper with a taller spur gear resulting in 20% higher contact surface area than existing 10T stepper designs, resulting in better wear characteristics and power transfer.
• Proper meshing of gears due to number of stepper teeth being divisible by number of planets (9T sun / 3 planets), which gives even loading on the planets / sun gear and improves wear characteristics and power transfer. Previous designs with 10T steppers had uneven loading on the planet gears.
