Lab Rocker

Currently operational, feedback always welcome

INTRO
This is a rocker I designed for my lab. Anyone who has worked in a a biology lab has used on of these to keep a sample from settling, develop a blot, or stain a gel, but the lab I'm in now didn't have one (everything was placed on the same shaker we grew cultures on, or even tapped to the legs of a shaking incubator). When I asked why we didn't I never got a good answer until I looked up the price of for one, and basically I got personally offended by what I saw.

SUPPLIES This is a full list of everything I used to make my rocker, brands are most likely irrelevant but if you choose a different motor you may need to resize the hole in the middle of the wheel, and the seat in the motor base to fit.

Besides an FDM printer you will need

Some sturdy filament (I used PETg, PLA + was just too soft)

A motor (Greartisan DC 12V 100RPM )

A pulse wave modulator or a potentiometer (Greartisan 1.8V-15V 2A DC Motor Speed Co
