Tinkercad Pencil Toppers

My 7th grade Digital Maker class made pencil toppers using Tinkercad. The students were taught 2 lessons prior to this task which introduced Tinkercad and how to make 'holes'. The size parameters were provided.  "Your pencil topper must be able to fit on a pencil. The measurements for the inside of the tube is 8mm. The outside of the tube should be 9-10 mm."

Supplies

Materials used are Flash Forge 3D printers, PLA filament, Tinkercad iMac computers, calipers and millimeter rulers.

Step 1: Create the Pencil Topper Base

Drag a cylinder onto the workplane. Make the cylinder 9-10 mm in diameter.

Drag another cylinder onto the workplane and make it a hole. Make the hole diameter 8mm.

Select both items, align them and group them to make the hole in cylinder 1.

Step 2: Add Base to Shape

Copy and paste the pencil topper base into a project that you have created or use the shapes provided in Tinkercad. I used a jet that was a prior assignment.

Step 3: Fit, Align and Print

Shrink the shape (jet) to fit the pencil topper base. Select all the shapes and use the alignment tool to align them. Export the .stl file and 3D print!

Step 4: Presentation

We put the pencil toppers in a prize machine at school. Students could earn or purchase our pencil toppers as prizes! We also included a positive message with each pencil topper.
