Lab Shakers for Agitation
3D printing with water soluble material is a great way to produce objects with complex geometry and overhangs. 3D printed PVA support material can take many hours to dissolve in water. An orbital shaker can help speed up the process and reduce clean up.
A Crickit Powered Lab Shaker
This DIY shaker uses an Adafruit Crickit, Circuit Playground Express and DC motor. The speed is adjustable with a potentiometer. MicroUSB port is accessible for programming. The unit is powered by a power supply for constant usage. With 3D printed parts, electronics and hardware, you can create a lab shaker agitator.
The parts used in this project are linked below. The Circuit Playground Express and Crickit are sold separately. Additional Jumper wires are used to create modular connections between components.
You'll need some additional hardware like screws and nuts to assemble this project. Note the different screw head types used. Mostly using metric M3 size screws. Flat head screws are used for creating flush joinery. Ball bearings are used to create the pivoting platform. Source them from your local hardware store or purchase online.
