Kinetic Sculpture V1
Introduction: Kinetic Sculpture V1
Hi All,
I got inspired by <PERSON> 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/
Step 1: What Do We Need?
* 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
Step 2: Spiral Design
* 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
Step 3: Spiral Wheel
* 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
Step 4: Gearbox Design
* 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
Step 5: Gearbox
* 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
Step 6: Backplate
* I used Freecad to design this
+ secure and hold the dc motor
+ holes for wall mounting
Step 7: Backplate Assembly
* 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
Step 8: Final Assembly
* Fit the wheels on the gearbox using super glue
* Wall mount it
* Switch on and adore 949
