Learning Scale with Numbers (1–10)

This fun and educational 3D-printed scale is perfect for helping kids learn numbers and explore basic concepts of gravity.

Each number from 1 to 10 is printed in 3.5g increments (e.g., 1 = 3.5g, 2 = 7g, …, 10 = 35g). Be sure to use the provided print profile for the numbers so their weights remain accurate.

No supports are needed for printing, and the scale’s assembly is straightforward. You’ll need six M3 12mm screws for the hinges—these will self-tap into the holes. Take care not to over tighten, as minimal friction is key. The holders on each side snap together securely, though you may need a gentle tap from a soft “THWACK” hammer. Once assembled, you’ll have a playful way for kids to grasp numerical values and experience how weight and gravity interact in a hands-on setting.
