This battery holder was inspired by https://www.printables.com/model/396692-einhell-battery-holder-v2 however I had batteries from Bosch, Einhell and Parkside so a holder for only one system was not good enough. Also I disliked that the spacers had a screw. 

So I designed a fully compatible solution that is easy to adjust to any battery system. Just take a few measurements of your battery and put them in the table in the included FreeCAD file. The CAD model will adjust automatically.
