Charge Spy for Wall mount for Bosch eBike Akku (PowerPack 500)

thingiverse

I refer to herbert_b1 with his construction of a wall mount for Bosch eBike battery (PowerPack 500), see www.thingiverse.com/thing:3066794. Herbert has cleverly included a window in his design, allowing the LED's of the charge level indicator to be visible. Unfortunately, this means that the display is limited and can only be viewed from the side. To resolve this issue, I designed a small part that redirects the diode signals via five "fiber optics" out of the holder, making them accessible for viewing from the front. This part simply presses into the viewing opening provided by Herbert. As an optical fibre, I used transparent PETG filament with a diameter of 1.75mm, which I inserted (with pliers) into the five hollow guides and cut flush at the edges with a cutter. Threading requires some skill, but the large diameter of the hollow tubes in the part (3mm) allows for easy insertion of the transparent filament around necessary corners inside the fiber guides. If necessary, grasp the filament as it exits the other end of the guide, then pull it back through to ensure no damaged filament remains. This method guarantees optimal light conduction. Check out the pictures of the finished part - I think it serves its purpose beautifully. Enjoy using it and thanks again to Herbert for the basic idea behind the wall bracket. @Herbert: I hope this is okay with you.
