Square gears from plywood
A friend said like acoo kie, his wife said some windows :) And yet they spin!
I did not come up with square gears, I just repeated. Recently I collected a CNC machine tool and I really wanted to cut out such gears from plywood.
For those who want to cut out such gears, I attach g-code for the machine. In the archive there are two versions of the gears and the source files dxf.
A dancing robot with a height of 60 cm. You can use costumes and accessories. There is wireless control, you can control the movements of the robot.
Today, instead of round guides, the printer received square, using a conventional aluminum profile tube with a cross section of 20 * 20 mm. Bearings roll along the pipe 623zz. All plastic parts were printed on the same printer before it was altered.
It all started with the fact that I had a daughter :) Now she is 1.3 years old and she has already learned to deftly sit down to her daddy on her knees and read a book. Each child, like an adult, should have his own chair. Searches in children's shops were unsuccessful, the chairs are all plastic and large or with a hole for the pot. We needed a normal chair for sitting, for a very small girl.
The eternal problem, which wire to connect :)
The 3D model of the fan is very simple, easily wound on a collet clamp. I put it on my CNC machine. The first launch proved to be very good, all the chips are scattered to the sides, clean under the cutter.
