By 3D4Kids


3d model information






Various depending on size of feet





Printing time:

Number of pieces:

4 per student


During this project, students will further develop their product (Gumball Machine) to create an individual look by creating their own feet and not using the Acrylic feet provided.

Learning objectives

Students will be able to:

  • Independently research different types of sweets to include shape/texture/colour
  • Personalise their product
  • Understand Tinkercad
  • Learn 3D printing techniques
  • Create and print in 3D STL models of their chosen sweet feet design.


Teacher preparation

Discussion of tools within Tinkercad and re-cap how to perform basic actions.

Discuss the variety of sweets – traditional – modern

Discuss how to transfer the file (STL) to Flash Forge Finder – individual basis when appropriate.

Teacher explanation

Re-cap the unit of work covering Gumball Machine – workshop techniques.

Discuss with students the shapes and colours used – students would have already carried out research as part of the project

Students can use images on line of sweets to assist in their drawing.

Student activity/Steps
