For the cantilever arm I needed a very light setup. @Deltaprintr mini hot end seems to fit the description. I designed custom holder to attached to the @Mark_Carew_OpenBuild mini v gantry plate.
@Shai_Schechter the M3 screw per drawing was supposed to be 16mm apart, mine is actually 15.3mm apart…
I’m surprised to hear it’s 15.3mm apart. Are you sure? Because all of our heatsinks are made the same, so I am not sure how one would be different.

Locked my caliper at 16mm and it seems smaller than that

Not sure if picture in comment can be zoomed in… So here I posted the pics https://plus.google.com/+StephenCia/posts/3KeSY3r8v68
Don’t know that that’s an accurate measurement. Looks much more centered at 16.00 than 15.3 to my eye.
It looks 16mm on-center to me. Easiest way to measure is to go from right side of one hole to the right side of the other (or left-left).
interesting thing to bolt the z to the wall. must have insane stability probably could get the machine to run fast, if it is all as stable. i have a few troubles on my simple metal with z wobble and that the machine shakes a lot when printing above 40 m/s especially with the bed upgrade i never go over. im always afraid that the heavier bed will cause the belt to de-attach mid print and im never home to watch my prints.
Yeah I realised there could be a better way to scientifically measure this…
@Step_Cia Hard to tell from the pictures, but it does seem the correct distance apart. A measurement of 0.70mm is really impossible to do by just looking.
In both pictures, the caliper is shifted right-off center slightly it seems. On the right hole.
Though I’m not saying you’re wrong, but it would need to be done properly under a microscope 
Here’s a trick. Zero out your calipers like normal. Take the inside measurement of one of the holes. Zero to that measurement. Then take an inner measurement to the outside of both (combined across). That should give you an accurate center to center.
Thanks @ThantiK Ok here you go 15.61mm apart.
It’s not really affecting me much since my holder is printed part so I can twist it a bit but if the holder were a mchined aluminum I can see it could be an issue…
