Thales (fast & easy, for school)

thingiverse

Thales base and angle, fast and easy to print, even on low-quality printers. How to: Print both files, and simply clip the angle onto the circular rail. It will still be able to move, and it lasts a long time. Keep away from heat and remove the angle after use, if you use PLA. Other than that: It just works. Idea: This is a physical object to dynamically show that no matter where you place the angle on the circle, it always is 90°. Vise versa, the (obviously) right angle is changed, as long as it travels on the circle. * If you like this, feel free to leave a <3 or a tip. That helps me provide more PLA for my students to work with. :) *
