Centrifuge for dram vials

thingiverse

This is a centrifuge for dram vials. It uses a 45-degree fixed angle rotor, and seats six vials. The drive system can use a variety of brushless DC motors. A minimum 20A ESC is recommended due to the mass of the rotor. There are parts specifically for 1806 and 2208 motors, which mount to the base plate. The centrifuge case consists of a main body, which the rotor base plate bolts into, and a lid, which is joined to the main body by a hinge, using two 1" 8-32 bolts and lock nuts. Both the body and lid have matching seats for magnets, to keep the lid down. There are also seats for 1/4" cube magnets in the base, to hold the centrifuge down, or it can be bolted down. For a user interface, there is a front plate intended to be used with a Nokia 5110 LCD display and a five-position joystick, interfaced along with the ESC to an Arduino pro mini. The back of the case has a hole and seat for a snap-in DC jack to provide power. The thread library is derived from https://www.thingiverse.com/thing:8793
