3D Print puzzle

I eventually ended up with the file above as the shape I wanted for my vertical pillars, but I don't think I can 3dprint that, as the bottom end will not build up correctly. If I stand it up, the middle bit suddenly goes out over thin air :oops:, So I got thinking how to reconstruct them so that they would 3d print.
The best idea I had was this

The sketch tries to show 2 pieces (one in construction geometry) which I would have to glue together as shown for the middle bit to get the 'wrap around' effect I'm looking for. I'd glue full circles on to them, but all this is looking very messy and gluey. The pillars have a 16mm diameter. I'm hoping for a better 3d printable way of doing it.

I'm intending to hand the printing out. The support would have to be lined up perfectly. Frankly, I didn't think that idea was a runner. It's one thing doing a bodge job at home, quite another getting some dweeb in a printing house to do it

If you want to glue things: why not glue the top cylinder? Make two spikes on the long bars and two holes in the cylinder so that they fit and then you can easily glue them together.

As an alternative you may think about a small flat at the outside and some chamfer so that you can print the way proposed by pl7i92LCNC but without using support. Printers can fairly well print up to an angle of 70° or even 75°. So there will not be much left.

a 3D printer is 65 USD Anet style
there is so mutch need in a single household for that kind of mashine
get you one and mak it yourself
if you can stay on PLA material

Not here in Ireland
That printer(which I'd like a link to, btw) IF they send to Ireland will have a hefty postage/courier charge (slow post takes months; quicker post takes $$; couriers tale $$$$!). ~Then there's 25% import duty into the EU on much stuff, and maybe VAT at point of entry if you're registered for vat, as I once was. Some things get in cheap, some couriers total the bill (article, freight, import duty) and then apply vat, effectively charging VAT twice, and vat on their bill's vat.
Rule #1 on Internet buying here is: Forget the US. It is (or was) cheaper from China.

The house has no need for a 3d printer. We're minimalists. I wouldn't have a scanner (in my printer) except I can't get a steady photo any more with only one hand on the job.

@chrisb:

I don't want to glue, but I've no way out of it. here's huge long panels for sides & roof getting glued as well, There is going to be an internal frame of 1"×1" planed soft wood, or approx. 19mm². That's what the 90º section out of the pillar is about. So I can glue to that frame, no problem. This is just getting as bad as one of those really messy Airfix kits? Anyone remember those? The worst stuff was the glue - it gassed you, gave you a headache, and melted the plastic :evil:

That's the pillars now. I'm going a two-piece route. Does it matter that I have some stray XZ axis showing up all over the place? How did it get there? I can't seem to get rid of it. If it doesn't affect o/p, then it will hardly matter, will it?

Go in the tree into Bodies 5, 6, 7, 8 and make the origin invisible.
