How would you draw this?

I often move things into place by changing a number, redrawing, looking at it all ways up and then repeating.

I work out the math, realise I got it wrong, then move stuff around using your method until I get it right.

I've recently dropped an amd am1 mini-itx board into my little wooden box and a real cheap quadcore chip.
Openscad renders reasonably quick.

My point was actually that the round balls and round linking rods would fit better in round sockets. Okay so the final f6 render might take a few minutes. But you end up with a more functional model. And the f5 redraws are pretty instant even with fn=100.

So no biggy.

But have to thank you for using individual facet functions. I had no idea that was possible and even wrote a polygon script to get round the fact that I could have a six sided cylinder.
Now I know different :-)

I'd have to say the biggest isue with openscad is the manual. It's written by someone who knows the program inside out and doesn't understand the simple fact that most people don't.
So any time I've looked at the manual I've come away thoroughly confused.
Whereas tutorials and forum answers have always made sense - thank god lol

One thing that does make it easier is to use diameters rather than radiuses. That way I don't have to remember that double or halve the radius. Just simplifies calculations.

That $fn - is great I can set it as a global variable so everything has 100 facets, and also assign a lower number for polygons to individual shapes.
You have no idea how much that helps me :-)

It works well with the chain. The pulley openscad file had to be changed a bit to make it remove less of the sphere so it held the chain better but other than that it seems fine.

For the first couple of hours running I had to keep adjusting the tension but after that it has stayed tight. I left it running like the video overnight with no problems or slipping.
