Puzzle

For class, we've been put into groups and given a task. We have to design a puzzle of 20cm x 20cm. Each member of the team must create an individual piece of the puzzle. By the end it has to fit together perfectly meaning we'll need to communicate and co-ordinate.

The requirements were:

• Must be 3D printed
• 5mm height
• 20cm x 20cm frame
• Each piece per group member must be unique
• 130g max material usage (26g each, assumption).
• Each team member has a unique requirement for their shape
• No space/gaps around the shapes
• Pieces must be easy to put together and remove, while not falling out of the frame when it is picked up (assume frame has no backing)
• Pieces can have holes inside the shapes (can assist with assembling and removing)
• Able to add a 'peg' or 'handle' to help pick up and put down the shapes in our puzzle
• Must fit neatly into a shipping box. The dimensions of the shipping box is 20.2cm x 20.2cm (2mm to assure it is not too tight) and 12mm tall, to fit up to 10mm puzzle and 2mm for instructions.

And each member of the team had individual requirments:

• The piece must have a triangle integrated into it
• Must include an angle that isn't 90 degrees
• The piece must have at least 3 changes in direction along one edge
• The piece must have one edge longer than 8 cm and one edge shorter than 4 cm
• The piece must include at least one smooth, curved edge

My first idea was something along the lines of this:

It was simple to design in Blender but we realised as a group that it would be quite hard to co-ordinate the design of it. If all of us have to make a piece, ensuring that they all fit together with such odd shapes would be difficult. Instead we came up with a simpler design that would be easier for us to co-ordinate. We decided to start drawing out designs and seeing what would work.

A much simpler design with specific measurements. Each piece is a simple rectangle with shapes added on and subtracted, the interlocking parts placed directly in the centre. It should prevent issues down the line by ensuring we have a standard template for each member to work off of. We moved to a Miro board to better co-ordinate.
