I love the ease of changing the front face on the IKEA drawers so I bought a Rationell drawer and worked on modifying it to fit a 12″ base cabinet. Below are some pics showing the mod.
Use this design and numbers to do any Rationell mod
Those are the pins that need to be marked out
Marked out the cut on Scotch Tape. More visible than writing on the actual surface.
Used a Grinder Cut Wheel to make the cut
Put the bottom back on after cutting it as well
Worked on the drawer face
Handles also from IKEA
