Original Braun electrical toothbrush base :
Our first Braun electrical toothbrush
came solely with the bare base.
A second one was bought after several months, for just a slightly
higher price, but this one came with a broader and stable base foot.
So I decided to provide a similar base foot to the previously acquired
toothbrush, as well.
After several measurements, 3D-models were created.
The base was modeled with holes for the brush-extension pins :
and the pin was modeled separately, to be added/glued later:
After printing two pins and one base, assembling by superglueing is
simple, just pay attention to the pin's orientation:
To improve print quality, the base was printed laying on its 'back'.
added some extra walls to prevent 'head-jumping' and
to be removed later .
