Practical 2

Week 3

Teammates Present: Trumann, Shawn

Written By Shawn

Date: 08 Nov 21

Location: Fablab@T11 

Objective:

  1. To look at the building steps and find flaws / optimization possible before building with acrylic

Key learnings: 

  1. Cardboard can be cut using a laser printer for precise cutting.

  2. Cardboard can be cut using different methods to allow for different variations of design.

    1. Seamless bends

    2. Bending the cardboard

Cutting Process (using metal ruler to measure and sketch):

Cut out pieces(using metal ruler to guide cutting):

Hot glue process:

Incomplete build:

Finished build (Top of build [without lid], Side of build & Bottom of build):


Improvements:

  • Increase height of container by 5cm to raise volume from 500mL+ to 700mL+




Materials Required:

  1. Cardboard Boxes

  2. Penknife

  3. Hot Glue Gun

  4. Marker / Pen

  5. Ruler


Procedures:

  1. Use Marker / Pen & Ruler to mark out the shape of the cut out of the prototype on the cardboard box. 

    1. Mark out 4 Rectangles of 4.5cm x 20cm & label a1, a2, a3, a4 respectively

  1. Mark out 2 rectangles of 4cm x 20xm & label b1 & b2 respectively

  1. Mark out 4 rectangles of 1cm x 20cm & label c1, c2, c3 & c4 respectively

  1. Mark out 1 shape & label d

  1. Mark out 1 shape & label e


  1. Mark out 1 rectangle of 5cm x 20cm and label f

  1. Mark out 5 Rectangles of 5cm x 20cm & label g respectively

  1. Mark out 1 rectangle of 3cm x 5cm & label h

  1. Mark out 2 shape and label i1 & i2 respectively 


  1. Cut out all the shapes using a penknife

  2. Assemble the shape using a hot glue gun in this order:

    1. Connect a1, b1 & c1

  1. Connect g, c2, a2 & b2

  1. Connect d 15cm from the top 

  1. Connect h, i1 & i2

  1. Connect a3, c3, e & c4

  1. Connect a4

  1. Connect f (Do not glue f onto prototype)
