4x 18650 LiIon Battery Box

I used TPU to print that case.
My goal was to store 4 batteries in the smallest possible way.
 

Print Settings (depending on your chosen material and printer capabilities)

• no support needed
• 0.2-0.4mm layer hight
• 3-4 perimeters
• 3-5 top layers

On kind request, I added the STEP File as well (hope it helps)
