BMW 2000-2006 key charger

thingiverse

This is a case for a Oral-B/braun electric toothbrush charging dock with slots for 2 BMW 2000-2006 keys on the top. These BMW keys were used from 2000 on on several models like E46, E39, E61 pre-LCI, E53, E85 etc. and the battery for the remote control is charged wirelessly - normally during driving when the key is in the ignition lock. The problem about them is if one does not use the 2nd key regularly, the battery gets empty over time and can also die. As it is "common internet knowledge" that these keys can also be charged using an electrical toothbrush charging dock I tried it with success. Since it is hard to place the key there I designed this case for it. Used charger is a braun/Oral-B type 3757 and the case is designed specifically for it. I had this lying around from an old toothbrush, so I used it. The model consists of 3 parts screwed together from the bottom.
