IKEA Lack side table leg riser 50 mm
A riser that slips over the bottom of each IKEA Lack table leg and adds 50 mm of height so a robot vacuum fits underneath or the table reaches sofa arm level. Lack legs are 50 by 50 mm, so the riser has a 50.6 by 50.6 mm pocket 30 mm deep with 3 mm walls, a solid 50 mm tall block below with a 2 mm chamfer, and a 4 mm floor recess for a felt pad. Printed with 4 walls and 30 percent infill each riser carries over 20 kg. Print it pocket up; a set of four fits on a 220 mm bed.
Lack legs are consistent, but the height you need depends on your vacuum or sofa, so a generated riser matches your gap exactly. In SpeakCAD you give the height and leg size, preview the risers in the browser at no cost, ask for a version that also works for Lack TV bench legs in the chat and download the STL.
