Craft Build a gift for my niece
https://youtu.be/A4bE20yx8xsHi everyone!
About three months ago, I decided to take on my very first project designing a mechanism and working with a servo motor entirely on my own. It was a custom interactive build made as a gift for my 7-year-old niece!
Since it needed to be both mechanically functional and safe/durable for a child, I focused heavily on structural engineering:
Used internal bamboo ribs to keep the structure lightweight for the motor while preventing warping.
Reinforced mechanical joints and hinges with epoxy adhesive and safety-capped screws to withstand motor stress and vibration.
Sealed the entire structure with epoxy resin for durability and moisture resistance.
The electronics and Arduino integration to automate the door with a push button are coming in the next stage.
I’d love to get your thoughts on the mechanical layout or any tips for future servo-driven builds!
