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

[curious aardvark]

yes but then it would blow the wrong way.
The indentations in the fan that I'm using to lock it in place, only go 7mm deep.
If it clips in without breaking the clip - all well and good. If not, I need to reverse the fan direction so i can turn it round and slide it into the clip :-)

Mk3 clip coming up - this one should do the trick.

The bolts lock it in nicely, can't fall out.

What is interesting, the 'live' preview on simplify3d is always ahead of the actual printer.
As these test prints just take 15 mins, running over usb.

That's 100mm/s at 0.3 layer height, imagine what she'll do with a cooling duct !
Might be able to risk 0.4.

Anyway that's it for tonight. off to find food :-)
