DIYbio Centrifuge V 3.0

thingiverse

We've expanded the length/width from 100x100mm to 104x104mm, ensuring our Eppendorf tubes now sit comfortably without touching the sides. If you downloaded the files before June 24, 2019, you'll notice the smaller version, but we've got you covered with an updated motorMount_V2 STL file. This new addition features hex spaces for M3 nuts to fit snugly in place, preventing them from loosening due to vibrations and making it easy to tighten bolts without opening the case. If the nuts don't fit at first, simply insert them as far as possible and drive the bolt in, just like you would with a perfectly fitting nut. **Introduction** We're proud to introduce our DIYbio micocentrifuge V3, a game-changing upgrade that's sure to revolutionize your lab experience. Check out this video overview for a closer look: https://youtu.be/Od_wNhkoEak Last photo shows our V3 prototype (left) alongside the V2 (right), giving you a glimpse into our innovative design. **New Features** 1. Our rotor is now lighter and press-fit, with both lowpoly and hi-res OPENSCAD versions available for your convenience. 2. The rotor is cleverly positioned below the platform, ensuring optimal performance and ease of use. 3. We've relocated the microswitch plunger to just below the platform, preventing accidental activation when the lid is open. 4. Our hinges have been strengthened for added durability and security. 5. A separate motor mount allows you to choose from various motor sizes, giving you unparalleled flexibility. 6. The micocentrifuge now boasts a smaller profile and reduced top-heavy design, making it easier to handle and maneuver. 7. The offset bolt-latch makes inserting or retracting the retaining bolt a breeze, saving you time and effort. 8. Our containment compartment expertly isolates electronics from the rotor, ensuring optimal performance and safety. **Additional Features** This innovative micocentrifuge incorporates a 12V DC motor, microswitch for auto-cutoff when the cover is open, rocker switch, and extra space for an Arduino Nano, giving you endless possibilities for customization and expansion. **Description** Our DIYbio micocentrifuge uses a reliable 12V DC motor and simple rocker switch, with provisions for adding a microswitch (16x28mm, no arm) and room for a micocontroller like an Arduino Nano to add timing and cycle functions. The original SketchUp 2019 file (.skp) is included, as well as the OpenSCAD file for the higher-resolution rotor, giving you everything you need to get started. **Instructions** To assemble your micocentrifuge, simply require friction welding (or glue) to seal the acrylic between the top/bottom of the lid. The rotor is press fit onto the motor shaft, and if it's loose, apply a tiny bit of hot glue for a secure connection. The hinges use M3x 30mm bolts and nuts, while any M3 bolt can be used to hold the platform onto the case (at the bottom). **Improvements Still Coming** We're continually working on enhancements to make your micocentrifuge experience even better: 1. A solid lid cover for those without access to acrylic. 2. An informative video demonstration/tutorial to help you get started. 3. Different rotor/motor solutions to improve balance and performance.
