I have hired a bunch of engineers to design a cog (amongst other components) for me to fit on my servo motor spline shaft over fifteen weeks for hundreds of dollars but they all quit after a string of misinterpretations. I ended up having to make it on Photoshop after taking a photo of the top of it coloured with a black marker and surrounded by toothpaste! This was so I could easily magic wand the exact dimensions of the internal teeth.
I tried to extrude it on Photoshop using 3D but the ‘Export as 3D file’ option only resulted in a faulty dialogue box blinking onto the screen for less than a second. Then I read forums that said I needed to render it first. Its a basic little cog but Photoshop said that it would take 4 hours to render, and my Solid State Drive Macbook brand new top of the range laptop reached 100 degrees Celsius (even with a mod to maximise fan speeds to 6200 RPMs) each attempt within around five seconds before I stopped rendering.
Has noone in the world made software that can simply allow me to extrude a basic shape or create cogs to spec?
I have spent weeks trying to find the answer and I have heard people mention the most primitive thing I have ever heard of - trace the shape by hand in Sketchup. With no other options, I tried, but the line tool kept doing whatever it wanted and it had no magnet at all. It was absolutely impossible. The internal teeth are 17T 8.8mm diametre. The external ones need to be printed in various configurations through trial and error to create an artificial shaft for my robot. I don’t understand why there are no tools anywhere on the internet that are easy to accomplish this.
What do you guys recommend? A proper realistic solution please.
Great. Now even this forum only allows me to paste a single image after it let me upload 2. I chose the toothpaste covered servo rather than the photoshop cog design.
