This is a Gridfinity 2x4x4 holder for the clipper guards of a Surker K7S-silver hair clipper. It has 3 narrow drops for the #A, #1, and #B guards, and 3 wider drops for #2, #3, and #4. The blade protector shares a drop with the smallest guard. Because the guards are a bit wider than a gridfinity grid unit, I made it 2 units wide and used the extra space for a place to put my haircutting scissors (Himart brand). The scissors have a finger hook which overhangs the bin, which was an intentional design because it works well for where I keep this bin.
This was modeled in OpenSCAD and Blender. I locally modified Kennetek's fantastic gridfinity-rebuilt-openscad to get the different sized drops, then added bevels and the front cutaway in Blender, and finally did some mesh cleanup with PrusaSlicer and Blender for the final export.
Not sure if this will be useful to anybody else, but you never know.
