Images of final designs showing alternatives. This is the first lampshade I made but there are endless possibilities for changing from the basic cube and square spirals.
Step 1: Drawing the Basic Shapes/ Spiral Designs for Laser Cutting
Demonstrates how to draw the spirals
Step 2: Jpeg of Pdf Showing Drawing the Spirals Sequence
I have tried to make it as clear and easy as possible for everyone to understand. Hopefully nobody feels patronised.
Step 3: How to Draw the Spirals
This PDF starts to show how to create the more complex drawings for the lasercutter
Step 5: Completed CAD Drawings for Laser Cutting Withas Little Waste As Possible
Waste areas are used for additional elements for the shades.
Step 11: Twist the Spirals 180 Degrees to Change Overall Design
locate spacer onto one centre peg of a spiral and twist 180 to locate it onto centre peg of other spiral. The twist also adds tension which holds spacers in place and creates an even twist. You may need to adjust some of the spirals as corners may snag on the other faces of the'cube'
Step 12: Make Sure to Use a Low Heat Bulb- LED or CFL Compact Flourescent
a bulb which gives of heat can deform the acrylic and even be a fire hazard and are less energy efficient.
