This 12 slot storage case will hold 12 LP-E8 batteries. The unit can be layed horizontally on desk or workbench for storage or it can be wall mounted using the holes on the back of the case.
I have printed with PLA and ABS. Use your judgement on the in-fill based on the strength you want. If wall mounting just snug down the screws, don't overtighten, depending on your infill you could damage the print.
Batteries not included
