Novena Heirloom – battery brackets and SSD brackets

I recently fabricated a set of SSD and battery brackets. Since almost everything about the Heirloom required a custom solution, there was only the question of how the bracket designs would work. The primary criteria would be that they make use of the peek array if at all possible.

I did find a couple of potentially useful SSD brackets, but sourcing them was all but impossible. The solution in this case is very simple. A majority of the extant brackets seem to rely on the threaded holes in the sides of the drives. But the ones on the bottom made more sense in this case.

So I just milled up some straight bars with mounting holes at the SSD and peek locations. Since there is really no penalty for simple flourishes on the CNC mill, I added a little curved detail at the outboard end of the SSD brackets.

The battery mount was another story. Bunnie designed a case elastomer strap for his Novena enclosure but it is not compatible with the Heirloom layout. The spatial constraints around the battery location are significant and were made all the more so after Bunnie and I came up with the peek-mounted fan/heat sink arrangement that sits right between the SSD and the battery.

I pondered the issue casually for a while and had a sense that there should be a way to use the peek array. It wasn’t until I came in one morning with the battery bracket at the top of the list that I was compelled to find a solution. I had a vague notion that the battery would rest against the inner front wall of the enclosure and so the front mount would have to mount to that same vertical surface above the battery.

Having set up the milling vice for the 1″ wide aluminum strap used for the SSD brackets, I decided to make use of the setup and designed a system of aluminum clips that would capture the back face and top front face of the battery. An o-ring winding its way between the three would join the three brackets into a complete solution for holding the battery in place.

I’ll post the complete assembly when the parts return from the anodizer and the final machining work is done on the base panel.
