‘Hold it’ is a project which is intended to be adaptable to Design Make Assignments undertaken by pupils following Resistant Materials or Graphic Products elements of KeyStage 3 or 4 Design and Technology courses.

The project focuses on the design for a Pencil holder, but could be adapted to any simple assembly.

Pro/DESKTOP enables pupils (and teachers) to communicate and model complex 3D concepts in a fairly straightforward but highly accurate and attractive way. This project covers the skills of ‘modelling’ and assembling two ‘objects’. The Pro/DESKTOP part of the project may preceed traditional design elevation sketches. It is hoped that following the Pro/DESKTOP stage pupils may go on to manufacture the design.


Context
The context for this project is to design a small, two piece pencil, ruler and eraser holder with opportunity to apply some design control. Simple shapes can be mass manufactured or made as one-off designs.

Problem
Design a desktop device that will hold a number of pens, a 150mm ruler and a pencil eraser. The design should include a vertical back panel to prevent accidental knocking of the pencils and to provide opportunity for ‘aesthetic’ designing opportunities.

Constraints
It assumes limitations as to sizes of materials allowing creativity but provides a common form of assembly for the pupils in the group.

Available are:

  • a fretsaw (scrollsaw)
  • hand tools
  • drilling machine ‘bits’ of 12 and 40mm. Diameter
  • the model will be made from a block of softwood 200mm long 80mm deep which is 40mm thick.
  • a sheet of 6mm. M.D.F. (or Plywood) up to 200mm square.
