Heaven help me - I've just bought a delta kit :-)

Yeah noticed with a test print that the springs will be an issue. Need to slide them all up a couple inches and lock them in place.

Well finally got simplify3d to bridge horizontally. Don't really understand why. But apparently it won't willingly bridge a perimeter wall unless part of that wall is considered infill.

So if you have a 1mm wall on a 55mm long by 7mm wide duct. You have to set it to 1 perimeter for it to know it can bridge the 7mm gap. If you have 3 perimeters, it prints the 1mm wall exactly the same - but tries to bridge the gap lengthways. Which do not work.
Logical ? Apparently to matheticians - which I am not.

Now i just need to get it to retract better to reduce stringing.
Although fan clips in nicely. And blocks the holes.
So, I'm going to use the first two hot end bolts. Don't think it' necessary to use all 4.
Once I've added that it's on to designing interchangeable nozzles.
And seeing if the pound shop has got the teeny tiny cable ties in stock yet.

I'm getting there lol

Okay this should be the final design. It's for a 30mm fan, uses the first 2 hot end bolts. Fan just fits over the columns and push fits good and tight. but can be removes fairly easily too.
So this basically doesn't use ANY extra screws or bolts at all :-)
