12 AA battery sockets.

I designed this battery holder because there are always some unused batteries at home, and one or two batteries often disappear without a trace or roll off the table and get lost. I wanted to store the batteries, but I didn't want it to look monotonous and boring. So I carefully created this model based on the actual dimensions of AA batteries in a 1:1 scale. It consists of four tubular structures, each of which can hold three batteries, for a total of 12 batteries. It's both practical and quite interesting.

The entire model is divided into four separate parts, which you can print in different colors separately, without the need for a 3D printer that supports multi-color printing.

Black parts: #000000

Gold parts: #a77052

White parts: #FFFFFF

It is recommended to print with a filling density of at least 60%. If you are looking for better strength and durability, it is recommended to use an 80% filling rate. If you want the finished product to be more robust and durable, you can increase the filling rate to 100%.

Under the condition that the filling density reaches 80% or more, the entire printing process takes about 18 hours to complete.
