I’ve been having a lot of issues tweaking my latest Reprap design, so I haven’t been able print a case for my LeafCAN SOC meter. Late last week, the printer was stabilizing, so I took a break to whip up something in OpenSCAD. It’s just a basic box, which I printed in natural ABS. I don’t like the sharp corners, so I’ve already redesigned it with rounded corners for the next rev. This print was just to test out initial fitment. This case is the absolutely smallest you can go, and still fit in all the electronics.
As you can see from the photo below, the header pins add considerable depth.
Also, in this build, I used female header pins to make the LCD detachable from the PCB, which added another centimeter to the depth of the case. The back has slots to engage various mounts:
Below, LeafCAN is clipped onto a suction cup mount, using the attachment slots:
One idea I have is to make vent clips, so allow it to be attached to either the center or left HVAC vents. But so far, my favorite position is inside the left corner window:
In the location above, it’s up high enough to see easily, without obstructing the view out the windowshield, and the A-pillar helps to shield it from the sun. The only problem is figuring out the mount. I’m going to try a print a holder to allow me to suction cup it to the corner window next.
The natural ABS gives it a cool glow at night. The photo below only shows the glow on the right, but it actually glows all around.
Although my vision is good enough that I can read the LCD comfortably, even in bright sunlight, I can understand how some people would find it hard to read. I’m going to look into other displays, but at about $8, these 16×2 LCDs are hard to beat.
