Arrowhead

Arrowhead model in 3D

The arrowhead is part of the Archaeological Dig lesson. Duplicate the model to print many arrowheads at the same time. 

Astronaut Toolkit

3D Toolkit

The International Space Station (ISS) is the location for this lesson. Students learn the history of 3D printing in space before accepting the challenge to assist the astronauts with replacing tools needed in their toolkit. Screwdriver bits and wrenches are needed and students design and then test their 3D prints. What other tools might the astronauts need while in space? Can they be 3D printed? Discuss what improvement can be made to the student’s 3D printed tools.

Barcode

3D Barcode model

Barcodes seems to have been around forever but they were patented in 1951 by Norman Joseph Woodland and Bernard Silver. The invention is based on Morse Code. It wasn’t until 1974 that the first barcode was scanned on a pack of Wrigley’s chewing gum.

Basic Dice

Basic Dice 3D model

Common dice with dots on its sides. The sum of the numbers on opposing sides is 7. The corners are rounded to increase the rotation of dice.

Basic Numbered Dice

Basic Numbered Dice 3D model

Dice with numbers instead of dots on the sides. The sum of the numbers on opposing sides is 7.

Basic Tensegrity Pyramid

Tensegrity Pyramid model in 3D

Tensegrity is a structural principle based on individual pieces under compression inside a structure that is under continual tension in such a way that the individual pieces to not touch each other while the tensioned pieces (for example, twine or wire) delineate the system’s structure. In other words, one is left wondering how the individual pieces seem to float in mid-air. This model contains the bars and top/bottom pieces for a pyramid type of structure.

Bear

3D model of a bear

Is it a Grizzly, a Black or Brown bear? Maybe a polar bear. You can print several of them and have a collection of various bear types. Just change the filament color for the type of bear you need

Big Gripper

Gripper

It will helps open tightly closed bottles. For printing, use a 0.2mm layer height to save some time. There is no post processing needed for this model.

Bone

3D model of a bone

This is a simple bone model that is the typical shape when referring to bones of any kind. 

Brick by Brick 1 3D model

Brick by Brick 1 

Contains individual brick and hinge pieces.

Brick by Brick 2 3D model

Brick by Brick 2

Contains six Lego®-style building block bricks of varying sizes and shapes with a traditional toy brick height.

Brick by Brick 3 3D model

Brick by Brick 3

Contains eight Lego®-style building block bricks of varying sizes and shapes each with a smaller height than the traditional toy brick height.

Casting Mold

3D Model fo Casting Mold

In this lesson, students learn what casting molds are and design their own mold. Then they use either chocolate, wax, soap or gelatin as casting material to see if the fluid filled the mold’s cavity completely. How complex the casting model is can affect the overall look of the created object.
