Parametric Customizable Furniture Riser / Lift

Updated 2026/01: added chopWidth and chopDepth to allow for cutting the base flare to better fit into corners. 

Updated 2026/05: complete rewrite adding many new features, old version available in the customizer by picking z-riser-202601

Needed some more risers so revisited and rewrote this fully parametric riser to handle basically any weird (flat) furniture leg geometry you can throw at it.

Included 3mf file has every riser seen in the cover photo but its expected you'll be customizing your own. 

New Features:

• Pill Shapes & Bowed Sides: can now do curved sides. Set the bow out value to -1 to get a perfect semicircle on that side.
• Independent Wall Heights & Thickness: lip wall thickness and height can be set for each side independently.
• Pass-Throughs (U-Channels): Set any lip wall width to 0 to completely open up that side, ie set back and front to 0 to create a U channel.
• Wall-Huggers: us the flush cut parameters to chop off the base flare or set that side to 0 flare so the riser sits dead-flat against your wall or baseboards without a gap.
• Custom Flare & Stability: You can apply the base flare uniformly, or tweak the left/right/front/back flares independently. Use a wide, flared base, on one side to prevent tipping for instance.
