Kinetic Sculpture V1

Hi All,

I got inspired by David C Roy's kinetic sculptures and wanted to make it for myself

Though he does not share any details/plans/blueprints of the sculptures, here are many who have tried to decipher the art....

After studying youtube and a few other people's work, I decided to make mine with skills and materials that were easily available

My Design

• Lightweight
• DC Motor
• 3d Printed gears

This is my version one, please share your comments and advice to improve this further

Update: Latest design is available on https://www.instructables.com/Kinetic-Sculpture-Flower/

• 3d Printer
• STL files - click here
• Foam Board or Sun Board - 5mm
• Superglue
• 70rpm DC motor
• 5V mobile charger
• Gluestick
• box cutter
• 4mm wooden dowel or iron rods

• To create the spiral design, I used freecad
• I recommend watching few tutorials on youtube if you are a beginner like me
• Initially created a sketch as above and then with padding, and added 11 more to create a spiral
• The initial dimensions were 80mm for handheld fidget spinner
• I scaled the same design to 30mm by scaling a clone

• Export the spiral wheel to SVG and print it
• Stick it on the foam sheet and then cut it out using box cutter
• Paint the spiral wheel with acrylic paint
• We will need to make holes at the center later

• Requirements
  • The 2 spiral wheels need to be rotated in opposite directions
  • The gears have to be on the backside similar to a clock
  • RPM for the wheels should be between 5 to 15, so that the patterns made are visible
• Based on the dc geared motor I found at 5V gave me 70RPM
• I used freecad to design the gears
  • 70Teeth M1mm
  • 20Teeth M1mm
  • 10Teeth M1mm
• I got 10rpm as output

• 3d print the stl files
• I am using 4mm wooden dowels as axels
• Fix the 20T first then the back 70T and then the front 70T
• 10T gear will be fitted on the motor

• I used Freecad to design this
  • secure and hold the dc motor
  • holes for wall mounting

• 3d print the stl file
• Connect motor with two-wire and the dc plug as shown
• In my first design, the motor's alignment was off by 1mm, so had to drill hole to adjust the alignment
• Fit the motor as shown
• Superglue the gearbox on the back plate
• Fit the gear 10T
• Test and adjust alignment
