Magnetic Rack
thingiverse
Magnetic racks for 1.5ml-2ml microcentrifuge tubes. Loosely based off the clear plastic ONT vacuform tube holder for expansion kits. The current model takes 12x6.35x3.175mm (or 0.5x0.25x0.125") magnets. Shims may be required for ideal positioning. Magnets sit vertically between the two opposing angled tubes. A vertical tube angle option is also provided for non-tapered tubes. Please let me know in the comments if you would like me to generate other angle/number models from the openSCAD code. If you don't have a 3D printer (or, alternatively, want a rack made of polished gold steel), see this shapeways page: https://www.shapeways.com/product/74BSKW66Z/magnetic-rack-for-1-5ml-centrifuge-tubes
