variable ratio steering rack 3d models

The extruder has a 7.5:1 gear ratio, is ready to print flexible filament directly and weighs only around 135 g including motor. This makes the Icarus printhead very lightweight, allowing for higher print speeds as there is less mass to move around...

There are also a number of spring mounting holes added to the rack to adjust the tension depending on the properties of the spring itself and the required coil braking force.See the video for details: See also: If you liked this thing - let me know...
