I recently attended a Tinkercad Basic Webinar. Earlier, I use to design on Sketchup have a fair command over it.

After the webinar, I realize that Tinkercad is well suited for students as it not only introduces us to CAD but also helps us to practice some mathematics lessons and therefore I like using Scale while designing on Tinkercad.

This Instructable is part of our final assignment and I'll be making a Mini Dustpan and Brush Toy for my study table. This will help me to keep my study table clean from Rubber/Eraser dust and Pencil shavings.

Supplies

Laptop or Computer
Internet Connection
Tinkercad Account
3D printer, filament and a paper cutter (if you are printing)

Step 1: Designing Dustpan

Log in to your Tinkercad account and click 3D Design (Left of your screen). Then click on Create new design.
Click and drag the ruler (Top right of your screen) to the Workplane.
Keep the workplane snap grid measurement to 1.0 mm (Bottom right of your screen).
Now, click on Box shape under Tinkercad basic shapes menu (Right of your screen) and drag it to the workplane.
Change the dimensions of the box to 30mm X 40mm X 12 mm ( L*B*H). Change X and Y value to 15mm and 0mm respectively. X and Y (See pic 1 above), are the distance of the box from the X and Y-axis respectively.
Next, click and drag the Roof shape under Tinkercad basic shapes menu (Right of your screen) to the workplane. Rotate it to 90 degrees clockwise and change its dimensions to 30mm X 40mm X 12 (L*B*H) and X and Y to 15mm and 0mm respectively.
Click on the box, then click on Duplicate and Repeat (Left of your screen). Next, click and hold on the box and drag the mouse backward to duplicate. Then click on the Change to Hole option.
Change the dimensions of Hole Box to 43mm X 34mm X 10mm (L*B*H) and value of X, Y, and Z (Height above workplane) to 3mm, 0mm, and 0.5mm respectively.
Now, select all the shapes (Ctrl + A) and click on Group to group all the shapes together.
Drag Half Sphere shape under Tinkercad basic shapes menu to the workplane. Change it to Hole and its dimensions to 5mm X 5mm X 3mm (L*B*H). Rotate it to 90 degrees angle. Then duplicate this Half Sphere and rotate the new half sphere to 180 degrees so that both the sphere faces away to each other.
Click on the half sphere facing toward left and change its X, Y, and Z values to -1mm, 7mm, and 1mm. Next, click on the second half-sphere and change its X, Y, and Z values to 38mm, 7mm, and 1mm.
Complete the Dustpan by selecting all the shapes and clicking on Group to group all the shapes together.

Step 2: Designing Dustpan Handle

Click on Box shape under Tinkercad basic shapes menu (Right of your screen) and drag it to the workplane. Change the dimensions of the box to 15mm X 46mm X 10mm ( L*B*H). Let X,Y and Z value to be 0mm.
Click on the box, then click on Duplicate and Repeat. Next, click and hold on the box and drag the mouse forward to duplicate. Then click on the Change to Hole option. Change the dimensions of Hole Box to 30mm X 42mm X 15mm (L*B*H) and value of X, Y, and Z (Height above workplane) to 2mm, 2mm, and 0mm respectively.
Now, select all the shapes (Ctrl + A) and click on Group to group all the shapes together.
Next, Drag Half Sphere shape under Tinkercad basic shapes menu to the workplane. Change its dimensions to 5mm X 5mm X 3mm (L*B*H). Rotate it to 90 degrees angle. Then duplicate this Half Sphere and rotate the new half sphere to 180 degrees so that both the sphere faces away to each other. Click on the half sphere facing toward left and change its X, Y, and Z values to 2mm, 10mm, and 2mm. Next, click on the second half-sphere and change its X, Y, and Z values to 41mm, 10mm, and 2mm.
Select all the shapes (Ctrl + A) and click on Group to group all the shapes together. Move this model 10mm away from the X-axis.
Click on Cylinder shape under Tinkercad basic shapes menu and drag it to the workplane. Change the dimensions of the box to 10mm X 10mm X 11mm ( L*B*H). Rotate it so that the cylinder is parallel to the Y-axis. Change X value to 18mm.
Now Duplicate the cylinder and make is a Hole. Then change its dimensions to 11mm X 8mm X 8mm (L*B*H) and value of X, Y, and Z to -3mm, 18mm, and 1.50mm respectively.
Complete the Dustpan Handle by selecting all the shapes and clicking on Group (Ctrl + G).

Step 3: Designing Brush

Click and drag Cylinder shape to the workplane and change its dimensions to 30mm X 30mm X 12mm (L*B*H).
Now Duplicate the cylinder and make it hollow. Then change its dimensions to 2mm X 0mm X 0mm (L*B*H). Select these shapes and Group(Ctrl + G) them to get a C shape.
Drag a Box shape to the mouth of the C shape. Change the Box dimensions to 30mm X 2mm X 12 mm.
Drag another Box shape to the workplane, 27mm away from the previous Box. Its dimensions will be the same as the previous Box.
Now, pull a Cylinder shape and change its dimensions to 1mm X 1mm X 26mm. Rotate this cylinder so that it is parallel to the X-axis. Change its X and Y value to 15mm and 28.50mm.
Duplicate this cylinder by selecting it and clicking Duplicate and repeat. Place each cylinder 1mm apart from one another. Repeat this till you fill the space between the two red Boxes.
Pullover a cylinder and change its dimensions to 10mm X 10mm X 15mm, Rotate it so that it is now parallel to the X-axis. The value of X and Y will be 1mm and 10mm respectively.
Extrude a hollow cylinder having a diameter of 10mm from this solid cylinder. The value of X, Y, and Z will be -4, 11, and 1 respectively.
Complete the Brush by selecting all the shapes and clicking on Group(Ctrl + G).
