Created on Tinkercad, these designs can be done in a variety of different colors and sizes before 3D printing or even using this as a draft to create them with your own materials! They are fairly simple designs, so they are especially beginner friendly!

Supplies

Tinkercad

3D printer or other materials to craft yourself

Step 1: Log Into Tinkercad and Select "Create New Design"

Step 2: Select Your Shapes

For the inner tube design, drag "Torus" to workspace. Drag however many you'd like to build your pencil holder.

For the sandcastle design, select "Cylinder" (3 of them),one "Cone" and two "Half Spheres" (or once again however many you'd like!)

(You will also need three more "Cones" which you can select later. These will be shaped into the triangle flags. The flag poles are made out of three "Boxes" that were shaped into rectangles. These can also be selected later so they don't clog workspace.

Step 3: Hardest Part: Stacking Your Shapes

Once you drag the shapes you want to build, you click on the small black arrow above the shape and raise it up.

Then, you're going to slide it to the place that you want it. Keep in mind it might not perfectly line up from the angle you are looking at, so look from all angles. To do this, move the cube on the top left of the screen labeled with "Front" etc.

Step 4: You Stacked Them! What Next?

Next, you are just making the particular design unique to you. Change colors! Adjust shape sizes! The "Torus" already has a whole in it, but for other shapes be sure to include holes, so that you can have the space that you need for storage.

There are two ways to do this:

Select one of the top gray shapes on the right, and place where you want the whole to be OR bring any shape into workspace and select "Hole".
