Car battery B3 B4 adapter

thingiverse

So I ordered a new battery for my car, and upon mounting it, I noticed there was a significant gap between the battery clamps on my car and the battery. It turned out that there are different types of battery mounting footprints, and my car has B4 (19mm height), while the new battery has B3 (10.5mm height). On the photos, the white battery is the new one, and the black one is the old one. This design fills in the difference between a B4 clamp and a B3 mounting foot. My new battery also had holes in the mounting foot, so I added a few pegs to this adapter to prevent it from falling off while mounting the battery. The pegs need some filing away to fit properly. I experienced issues generating the STL file; I had to redo the generation of the STL several times because sometimes layers were missing. However, printing from the STL that I added resulted in no problems at all. To make this adapter strong, I printed it with 100% infill.
