**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: 1. 12V DC motor power added for increased efficiency; 2. microswitch automatically shuts off when cover is opened; 3. high-resolution (400 sides) rotor based on: https://www.thingiverse.com/thing:2479765; 4. rocker switch included for easy operation; 5. extra space provided for Arduino Nano and; 6. 2 cover options: solid 3D printed & acrylic window version (version pictured). Description It uses a reliable 12V DC motor and an intuitive rocker switch. It also has provisions for adding in a microswitch and enough room for adding in a microcontroller (like an Arduino Nano) to add timing and cycle functions. There are 2 versions of the cover available. One is a solid 3D printed cover. The other is printed in 2 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. The rotor has been greatly improved from the low-poly original rotor 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 slightly modified to be more even. The OpenSCAD code (.scad) is also included. The spindle connector for the rotor is temporary. We're working on something better 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 is still in progress. Come back for the rest of the files, photos and video for the working centrifuge and links to build tutorials.
