When storing many small items such as screws or components in a gridfinity rebuilt bin, there's always a risk of spilling. This lid / plug fits onto the standard 1x1 bin with one or two compartments and a label tab. The plug can be inserted and removed again with little force, making it convenient in everyday use, but stays in place even when shaking the box upside down.
Notched edge for secure fit
Wider top edge to avoid insertion too far into the bin
Angled edge on one side to avoid snagging the label tab
Max ~1mm gap, no components can fall out
Handle for easy removal of the plug
Not stackable (duh)
Printed with (Elegoo) TPU 95A.
Designed in FreeCAD, original CAD file attached. Somewhat parametric using DynamicData workbench.
