Raise a table, desk, sofa or BBQ grill to a height that is actually comfortable — a few centimetres make all the difference for tall people. Print one riser per foot and pick what each foot is: a solid leg drops into a snug rectangular pocket that keeps it from sliding off, while a caster or wheel parks in a concave cradle matched to its diameter so it cannot roll away. The rise you choose is the exact height added in both modes, so mixed feet lift a piece evenly — two wheel cradles plus one leg pocket level a kettle grill. A wide base flange (auto-widened on tall risers) keeps everything stable, and the block prints solid and support-free.
What this riser holds. leg: a solid furniture leg sits in a snug rectangular pocket whose walls keep it from sliding off. wheel: a caster or wheel parks in a concave cradle matched to its diameter, so it cannot roll away. Print one riser per foot and mix both kinds at the same rise — e.g. two wheel cradles plus one leg pocket lift a kettle BBQ grill evenly.
How much height the riser adds. The leg's foot (or the wheel's contact point) ends up exactly this far above the floor, so use the same value for every riser under one piece of furniture.
Leg mode only: the leg's cross-section along one side. The pocket adds 1.5 mm of clearance per side, so measure the leg itself. For a round leg, set width and length both to its diameter.
Leg mode only: the leg's cross-section along the other side. Equal to the width for a square or round leg.
Wheel mode only: the wheel's diameter. The cradle's arc matches it (plus 1 mm of clearance) so the wheel sits parked and cannot roll out. A typical furniture caster is 40-75 mm; a kettle-grill wheel is about 200 mm.
Wheel mode only: the wheel's tyre width. The cradle channel adds 1.5 mm of clearance per side, and its end walls stop the wheel sliding sideways off the riser.
