Part 1; Hotend holder.
So to begin the build of my hotend holder I looked through my collection of old motherboards and found a decent CPU cooler that I could change into something usable as a hotend cooler and fan mount,
I was a bit fast when mounting it up on my mill, so I forgot to take a picture before the machining started, I basically had to remove a recess they had made on the CPU side, I guess it was there so the cooler would not hit the CPU socket.
After taking this picture I got a bit excited and forgot to take pictures of the 2mm deep pockets I milled in it to fit against the flanges on the hotends, the holes I made to mount it, the cutting to half the size of it and the surfacing on the other side to get rid of some of the fins, but here it is with the hotends put into the slots, I managed to get them to fit almost like Lego's on the first try. (I was a bit pleased with myself, I must admit
)
During this process I had drawn up the rest of the holder in Sketchup, the main mounting bracket was to look like this;
this was designed to make use of a 16mm aluminum plate I had from a previous project, so after some fiddling around in the CAM software I was ready to mill.
A LOT of alu-chips later I designed the hold-down clamp and Bowden-connector mount to be made out of 8mm Lexan.
And after some more machining and threading some screw holes this is what I have:
And with the Cooler attached, I will print a fan duct when I get the printer up and running
I might also reduce the size of the cooler, it sticks out quite a bit now
