I made this model to replace the broken drawer “rails” in my kids' dresser:

The dresser is RAST by IKEA, but the attached OpenSCAD can be used to adjust it for other configurations.

For more stability around the pegs I printed the rails with the pegs on the side, which requires adding supports.

Other models

After finding out the name of the dresser I found existing rail replacements:
