Liked the design Mfischer79 made and needed a case for 3 batteries so i decided to remix his model. Feel free to share your make here as i love to see other peoples prints!

I printed the model with supports for the notches where the battery locks, however i saw that it was uneccesary and can be printed without supports.

Print settings:

0.2 Layer height

15% infill

No supports

I am a beginner in Fusion 360 so the model might not be perfect but it functions correctly.
