This item looks like a clock, except that its face displays distances in centimeters, inches, meters, and feet rather than times.
To use the device, you roll the wheel across the item that needs measuring. As the wheel moves, the measuring hand moves as well, tracking how far the wheel has traveled. If your distance is greater than one rotation, the device also tracks how many circuits it has completed. Once you've measured the entire item, multiply the number displayed on the face by the number of rotations to find the total distance.
Not only is the UGears STEM LAB Curvimeter a working opsiometer, but it is also one that you can easily assemble yourself. You don't have to worry about getting glue everywhere, and you don't need any special equipment. The parts are precut, although you may need a knife to loosen a few from their boards, and if you don't remove them carefully, use sandpaper to smooth down the edges. Additionally, when the gears stick or don't fit, a little candle wax on their edges takes care of the problem.
Model Size: 4.5 x 3.3 x 6.6 in (11.4*8.4*16.8 cm)
Package size: 8.1 x 7.4 x 2.5 in (20.5*18.8*6.4 cm)
