So this job ended up as a bit of a head scratcher, as it forced me into finally using fusion 360.
I could not think of any way to work out the angle of the cup I would need to hold the sphere at the requested depth. Even after a good googling I could not find a way to work it out…
That’s where fusion 360 came in. I’ve had it installed for months, but have done literally nothing with it, so although my project was pretty simple it wasn’t the easiest task.
Obviously it would have been easier to make a round pocket at the correct diameter so the sphere sat at the required height/depth, but the customer requested a fairly snug cup that the sphere could sit in.
