DIYbio Centrifuge V 2.0

cults3d

New version now available. See here for V3: https://www.thingiverse.com/thing:3702648. WARNING: ALWAYS OPERATE THE CENTRIFUGE WITH THE COVER CLOSED. This is version 2.0 of our previous F.Lab DIYbio centrifuge: https://www.thingiverse.com/thing:1175393. Video demonstration is here: https://www.youtube.com/watch?v=rTMLX00tXjc. Features: Incorporates a powerful 12V DC motor for efficient operation. Equipped with a microswitch that automatically cuts off power when the cover is open, ensuring safety. Fitted with a high-resolution (400 sides) rotor based on: https://www.thingiverse.com/thing:2479765, providing accurate results. Boasts a convenient rocker switch for easy control. Includes extra space for an Arduino Nano to add timing and cycle functions. Offers two cover options: a solid 3D printed cover and a version with a removable acrylic window (version pictured above). Description: This centrifuge utilizes a 12V DC motor and a simple rocker switch. It also has provisions for adding in a microswitch and enough room for adding in a micocontroller (like an Arduino Nano) to add timing and cycle functions. There are two versions of the cover available. One is a solid 3D printed cover, while the other is printed in two sections and friction welded or glued together with a piece of acrylic in between to create a window (pictured). The original SketchUp file (.skp) is included for users who want to modify or customize the design. The rotor has been significantly improved from its low-poly predecessor thanks to the OpenSCAD model published by Thomas Kircher. His code has been slightly modified from around 200 sides to 400 sides and the dimensions have been adjusted to ensure evenness. The OpenSCAD code (.scad) is also included for users who want to experiment with different designs. The spindle connector for the rotor is currently provisional, but we are working on a new design that will leave the rotor perfectly balanced. For now, it uses a sawed off 5mm diameter bolt and a nut glued into the spindle connector. This project is still in progress, and more information, photos, video, and links to build tutorials will be added soon.
