That's 4mm wide 0.5mm thick and has an ID on 120 mm.

Due to the size limitations of my 2K printer: XYZ:130x80x150, I need to print this (near) vertically and rotated to the diagonal.

If I use the auto support genration of a slicer (here chitubox) I get something like this:

Which seems to be both overcomplicated and at the same time very flimsy.

I'm consdering using a hand constructed support structure something like this:

As this is going to take almost 11 hours to print and I never printred any this large and flimsy before; I'm looking for reassurance that it might work? Or, alternative suggestions for support structure?

I realise that printing something like this successfully will come down to the printer being set up correctly; but I've previously printed (much smaller) flimsy things like this:

(0.5mm holes on a 1mm spaced hex grid in 0.25mm thinkness.)

So I think my printer must be setup reasonably well.

OPinions and suggestions sought!

Thanks, Buk
