Wall mount (expandable number) for AliExpress car battery charger (EAFC/Narzrle)

thingiverse

I ordered some cheap car battery chargers from AliExpress to maintain some car batteries that are standing around, so that they don't die. I wanted it tidy, so throwing the chargers on the ground of my workshop was no option. It fits perfectly and the charger(s) can be snapped in. As I have more of those chargers, I wanted to be able to line them up correctly, keeping the same distance everywhere. While at it, I found that aligning the chargers in one line would put the air outlet of the previous charger next to the air inlet of the next one, potentially creating a danger as the chargers would get warmer and warmer air from the previous ones. So I used the filigrane alignment helper and designed a deflector shield upon of it, next to each air outlet, which redirects the warm air horizontally away from the wall and the chargers, while the colder air will be sucked in from below or above. The STL provided contains both, the holder and one connector to a potential next charger, as I designed it in a way that it geometrically fits inside. The geometry is suitable for all chargers that have this kind of case (note the two grooves on each side) - they are sold under different brand names with red/black or yellow/black cases around 10 euro on aliexpress. BE AWARE that there are similar-looking ones that don't have those groves and they wouldn't fit. As the chargers come with quite short cables towards the battery, there is no use of stacking them vertically, so I made it only horizontally expandable so that the cables can reach the batteries on the floor while the chargers are being mounted on the wall. Additionally I added holes for zip ties in each column, so that the cables can be neatly organized. Not that they are designed to be printed without support, that is why you should set either no support or "touching build plate only" if you want the small clip feature for the connector parts to be supported.
