I could not find anything matching the size, and being lightweight, after 6 prototypes, that's what I came up with.
The idea is to create a photo wall. For now the plan is to use double sided tape. Maybe I'll add a hanger module for the first raw. Let's see.
Please print upside down. I'll adjust the model in the future. The gcode is ok out of the box.
The author marked this model as their own original creation.
