This design is tailored for the "Baseus MagSafe Powerbank with 6000mAh," although it may also fit other powerbanks.

The stand consists of three main parts that are easy to assemble; both the pole and the base feature a small notch, useful for aligning them before gluing (I recommend gluing to prevent rotation and wobbling).

This is my initial design, which may contain some errors and require adjustments. I am hopeful that individuals with more experience will take an interest in this design and enhance it.

Have fun.

I personally only used tree support for the "pole" and the "main body" parts.
Be sure to position the "main body" in a vertical position to avoid useless troubles with supports.
the print works fine with very low infill percentage (personally 10%) since the center of mass is well positioned it doesnt need excessive weight at the base to stay put.
