This is my first model on this site. The model should print without any supports if printed flat. I used PETG and 25% infill so it has some weight. You can also pause the print and add sand to give it more weight. The edges are not round just for the case to be aesthetically nice.
For the hot shoe I use these from AliExpress: https://vi.aliexpress.com/item/1005005629614101.html
For the middle one I used this one: https://vi.aliexpress.com/item/1005006124935243.html
And you can also use this to extend the amount of hot shoes available: https://vi.aliexpress.com/item/1005006358024959.html
You can edit the model as you like BUT tag me to see your ideas.
