A 1x2x3 Gridfinity Bin that can hold a Meike MK-S-AF3B Macro Adapter for Sony Cameras. Built on top of kennetek's Gridfinity Rebuilt in OpenSCAD.
My code for this is also open-source. See it on Github.
The author remixed this model.
I used the original Gridfinity Rebuilt model for the body of the bin but used my own code to cut out slots for the batteries.
