3D Printed DIYbio Orbital Shaker V2.0

This is our second 3D printed orbital shaker design. It is significantly larger than the first, and includes a very useful rail system to hold containers on the platform during operation.

Orbital shakers are used in labs to agitate containers using a circular motion.

All the files for this project along with a video of the shaker in operation can be found on Thingiverse here.

3D Printed Centrifuge V2.0

This is our second 3D printed centrifuge design (designed in SketchUp). It uses a regular 12V DC motor, a toggle switch, a microswitch to automatically cut power when the lid is opened, and an acrylic panel to allow viewing of the centrifuge when in use.

All the files are available on Thingiverse here.

3D Printed Electric Screwdriver

This 3D printed electric screwdriver uses a 5v 9g servo converted for continuous rotation, an Arduino Nano, and a thumb joystick to actuate the servo forwards and backwards.

The design went through several iterations including a cordless version that turned out to be a bit too bulky.

A voltage regulator transforming 9v into 6v gives the servo just below maximum voltage, speeding it up.

A lot of work was put into stabilizing the bit. This included the most recent version which uses two instead of one 608zz ball bearings to straighten things out.

All the files are available on Thingiverse.

Arduino-Driven 3D Printed Aquarium Automation

For more information about our prototype, follow the aquaponics build log at HeliosLabs.blogspot.com. The model was made in SketchUp, converted into .STL format and imported into MakerBot's MakerWare software for 3D printing.
