Do I get a prize for a Virtual entry? For a small fee I can provide the STL file so that Neil can print one for everybody.
Or as it might look in clear plastic:
The decorative holes spiral vertically up the inside of the candlestick. Can anyone suggest a way of producing an object like this (full of twirly holes) without using a 3D printer to build it up layer by layer?

So how many materials is that? You just aren't taking this seriously, are you?
Candlesticks made from mild steel, yellow Dymo tape and acrylic tubing & rod. All found in the scrap box, indeed the candle was marked ‘Decimal currency 2p’, so it is at least 40 years old. The steel bases could also be old CDs. If you don’t have any, get off to your local charity shop and buy a couple of Barry Manilow or Pan Pipes CDs. Either way, they are resistant to tipping, in the choppy waters of the Norfolk Broads or in order to withstand the celebrated Grand Union Bore. They are rather like a Captain’s Decanter, at least if you are captain of a Monitor… I had the had the idea at 7am Thursday morning and the job was done by 5pm. If you don’t ‘get it’, they are modelled on canal boat engine exhaust stacks. My lathe wasn’t big enough to face the ends, not having a Steady, but I realised I could square off the ends in the mill. Acrylic resists burning, but melts, so it should be safe, with care.
Then, on Friday, I had another idea, in collaboration with Mr Kipling, using preassembled foil, pastry, filling, and icing. The cherry was surgically removed and a pin drill used to mount the candle-holder without cracking the icing. This had the advantage that I could eat them afterwards, although the candles were a bit chewy. It took longer to find the Cherry Bakewells in the local shops, that it did to make them into candleholders.
Well I'm going to knock a point off for using Cherry Bakewells instead of Mince pies, though sending me the rest of the pack of Bakewells could see your score reinstated
I think he's cheating by trying to get two entries in one. The tarts don't count though as removing the cherry means they only have one ingredient – 'bakewell'.

However, I have to say he's taken it more seriously than Dave (S.O.D)
Whilst I admit many of my posts are nothing but hot-air, surely this entry must be serious:
There are two of them. The other blew away. You can trust me: I'm a doctor.

if you were half as good with a lathe and milling machine as you apparently are with image editing software, you'd have had a proper pair of bloody candle sticks made long ago!

I've hit problems with the Duffer's Turbo self-levelling Draught Proof candlestick and may not finish off fully to expectations.
First, the cat's contribution:
This is my return for feeding the vile creature. Luckily I was able to hide the damage.
Here's the pile of bits ready for assembly:
The spring carrier keeps the flame at the same height as the candle burns. The candle sits inside a glass chimney and is fed with air through the base to reduce the chance of being blown out. Hot air is supposed to spin the fan. Sadly I've run into big trouble balancing the fan : much harder than I thought so I'm back to the drawing board.
In Fusion 360 the design looks like this:
In practice:
And with the fan supports in place:
So far I've not managed to balance a fan on top for more than a few seconds let alone have it spin. I may pretend that the spike on top is a lightning conductor and hope that no-one questions it!
Gently punch a depression into the underside of the fan blades using a broad head centre punch or similar, it will sit easier on the lightning conductor then.
Sit the blade over a plate with a small hole in when you punch the depression so it only causes local movement of the fan metal.
That may well then also show up where the blades are heavy, by them dipping to one side when mounted on the lightning conductor.
