Hello all,
The second prototype has been ordered. It will be aluminium 6063, anodised black, have a brass plate, and be mine.
There are a number of changes between first prototype and what hopefully will be the design used in the GB, which I'll roughly disclose here for the sake of transparency:
- plate external radius increased marginally (may add some additional cuts to this too before ordering a bit more locally)
- front height lowered marginally
- USB height raised even more marginally
- cable routing changed slightly into having two levels
- added some engraving beneath the weight
- internal top chamfer decreased
- USB hole chamfer decreased
- bottom chamfer increased to be consistent with the top
- gasket mounting points changed
Regarding the last change, the previous mounting points led to some problems with the 50A o-ring towards the top-left and top-right corners, as the points in those corners were significantly further away from the left/right case edges than the ones on the bottom. I discussed this with Elaine and she kindly let me use the Unikorn's mounting points as well as giving some very valuable design advice which I am very grateful for.
