When putting the IKEA RIGGA clothes rack outside for drying the clothes the wind can easily push the whole rack around due to the attached wheels that don't have any break functionality.

As such I designed those simple wheel blocks to prevent this from happening.

Due to their simple nature and since they are meant chiefly for function, not for smooth surface design I printed this with 0.3mm layer height on PETG. Due to the effortless design, no support material is needed.

For those among you that want to block different wheels with different diameters or spacing the trivial OpenSCAD model is also attached for modification.
