Laser cut from plywood 200*200mm 3 mm thickness
This is a study case for practicing in 3D modelling, creating surfaces for laser cut. I will try to complicate the task for myself and try to make a moving figure.
By Rhinoceros 8. Main idea was that turning "key" you also can turn a hand. Basicly i thought about words in the cirle but modelling take a lot of my time and i forgot this idea.
Important to shop how i've made a gears. Designing gears that can rotate is not such an easy task. in order not to waste extra time, I found a workaround - a program that simulates gears.
this is a free software without installation where you design your gears. because i have no time to discover whole functions of it for export stl model - i've made a screenshot, took it in Rhino, circled and created a surface from which modeled 3D models. This programm i wil add in file directory in this repository.
Also you can see how geaars can move by this software.

Formally and in reality, the task was completed. But, despite the fact that the object and the gears are moving, there are several nuances why I do not consider the project 100% successful:
-
Parts broke during their extrusion from the wooden plate - it was necessary to make the jumpers thinner;
-
Due to the fact that the connecting circles, which were supposed to hold the structure as a single whole, turned out to be too narrow - they broke and the gears moved apart on the plane;
-
it was worth making the lower circles, which I made in order to reduce friction of the indicators on the surface, with the same tolerance as the upper ones - they are too loose for me;
-
at some point I was tired of this project and I needed moral strength to move on. I’m not sure that I’ll want to bring it to perfection, but the experience gained during the task was useful
