Eppendorf Centrifuge Hub

thingiverse

A centrifuge hub is available to accommodate four 2.5 mL Eppendorf tubes; it has been tested up to 10,000 RPM. To assemble this hub, follow these steps: laser-cut one central hub and four petals, then tap small M3 threaded holes on the petals. Finally, screw the parts together using four M3 screws (length: 15-20 mm). If you are creating a dremelfuge version, ensure that the center hole diameter matches your device's shaft diameter.
