D-Bot KALLAX feet extendsions

These simple extensions for the IKEA KALLAX allow to place the large 300x300 D-Bot saveley - the large version of the D-Bot does normally not fit on the 39cm of the KALLAX.

Print them tuned 90° sideways normally no support needed.
Use washers if possible to protect the part from ripping appart.

Comments and improvement suggestions welcome :-)
