Rubber isolator

thingiverse

I upgraded the stepper motors on my Hypercube 3D with rubber dampers and they effectively silenced the printer, but unfortunately caused the motors to sag due to increased belt tension. To address this, I printed out the angle adjustments which worked beautifully, yet introduced a new problem - metal touching the motor, resulting in a noticeable increase in sound volume. To resolve this issue, I flipped the motors around, secured them with glue and nuts, and utilized longer screws for additional support. Additionally, I employed a custom-made piece featuring a rubber foot to fully isolate the motor from vibrations. I further reinforced the setup by adding an extra nut to the longer screw where it connects to the 3D printed component. With these upgrades - dampers, the new piece with a rubber foot, and stepper smoothers in place, my printer is now remarkably quiet, with only the sound of the fans audible.
