Bespoke Handles for Magic Money Box

By 3D4Kids


3d model information






Various depending on chosen design however each handle must fit into a pre-drilled 5.5 mm



Printing time:

1 hour

Number of pieces:



During this project, students have been using various techniques to cut, prepare, shape and join various materials. Students would have used various tools/machines to prepare the mild steel including use of the brazing hearth. Students would have used various hand/portable and fixed machinery to prepare the wood and plastic being used to construct the money box.

Learning objectives

Students will be able to:

  • Understand Tinkercad
  • Learn 3D printing techniques
  • Create and print in 3D STL model of their chosen handle design
  • Complete making of Magic Money box with handle
  • Understand the importance of considering Ergonomics/Scale/Proportion when creating a product

Teacher preparation

Ensure all students have their Magic Money Boxes complete – only having the handle to add to their products. Ensure all boxes have the 5.5 mm drilled in ready for the printed handle.

Teacher explanation

Re-cap the unit of work which has been covered – the making of the Magic Money Box. Discuss with students the finishing touch of the box – their individual handles. Discuss with students the importance of carrying out research before sketching ideas. Discuss with students the overall size of the handle and what would look best with the Money Box – Scale/Proportion. Discuss Ergonomics in relation to the shape of the handle they will design.

Student activity/Steps

Step 1: Students to research different types of handle shapes – create a mood board from found images on the internet.

Step 2: Students sketch out the type of handle they would like to add to their individual products – add annotations and decide which design (shape) would look best on their products

Step 3: Student to draw on Tinkercad their chosen idea

Step 5: More able students might consider the texture of their handle and adapt their drawing.

Step 6: Students to export their final design to Flash Forge Finder

Step 7: Students scale their drawing to allow the handle to fit in the 5.5mm drilled hole within their product.

Step 8: Students to print their handle in their chosen colour to match/compliment their Magic Money Box

Step 9: Student to attach their handle and photograph their product.

Step 10. Students to complete the write up in their Production Logs on the processes they have just carried out.
