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.
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.
The eternal problem, which wire to connect :)
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.
This small turntable is needed when you need to photograph something or shoot a video in 360 degrees. For the assembly you will need an old CD-drive, a couple of pieces of plywood, a box for batteries, a switch, wires and other trifles.
This is my first CNC machine assembled with my own hands from available materials. The cost price of the machine is about $170.
