Fresh off the Thunder win Saturday night....I spent some of today putting together pump prototype #2. I recut some aluminum pieces, and this time I decided to go ahead and put a coat or two of black spray paint on them...just so the bare aluminum wouldn't be so distracting. Here was the highly calibrated and controlled painting environment setup for the evening....

Using this paint tonight....

One coat.....

Two coats.....

...and then rush inside to put it together before it's even dried. You'll notice I painted one of the Corsair fan accent rings black also, so that when I get back to choosing the fan colors I can use that one.

Several people had asked about decoupling the pumps, and this is what I'm using right now. These rubber vibration dampners come with the EK D5 mounting kit. The pump tops screw into these, and the frame I'm building screws into the other side of these. That way the frame is never touching the pump.

Here it is put together. The paint wasn't even close to dry so I really buggered it up doing this....but it still makes it less distracting fhan the bare aluminum when trying to picture what it would look like. I'm still excited about the 3d printing idea for a pump stand and I'm exploring that....but if I end up doing an aluminum version, I would definitely powder coat the final version.

The differences in this version are:

1) I lowered the top pump about 1.25 inches from where it was last time, and decreased the spacing between the two pumps. I knew it needed to be lower, but you really can't tell if you've done it the right amount with building a prototype.
2) Shortened the front side of the "T" brace at the bottom. Before, the base stuck out way in front of the pumps. Now...I only have it extending just a little bit in front of the frame. It still stands on it's own even with the shorter base.
3) Eliminated the horizontal brace I had between the pumps. It just doesn't need that since both of the pumps serve as a brace between the two frame sides.
4) Added a vertical / diagonal brace that extends from the middle of the pumps stand down to the back of the bottom brace.

Here is what the first version looked like:

An improvement. And much sturdier. This one is solid with that back brace.

This one turned out to be just about the right size also. Here are some pictures in the case. Notice how there will be just enough space for the reservoir (mounted and elevated eventually) to the right of the pump tops and in the front window.

And with the window on you can see that the pump tops are fairly well centered in the window now. Just what I was picturing.

More info on the 3d printing tomorrow......
