Ikea FRIHETEN Sleeper Sectional Legs for Robot Vacuums

thingiverse

This raises the Friheten sofa enough for robot vacuums to clean under it on carpet, specifically ones that are ~100 mm tall. It should work for the entire line of Friheten sofas. The robot vacuum will not be able to clean the rear half of the pull-out section of the sofa. There is a wood support going across this section that would require an additional ~20 mm height to clear. At this height, metal plates would need to be bolted to the sides for wheel extensions. You can pull out the movable section and run the robot vacuum under the sofa again to get this missed area. Step files are included with changes made to: * Rebuild from scratch in Fusion 360 * Legs now raise the sofa 110 mm instead of 100 mm, compensating for sinking into medium pile carpet * Built for M8x20mm bolts as originals are not removable * Removed cut on Wheel Extension for fabric BOM includes: 7 M8x20 mm Bolts https://www.amazon.com/uxcell-Thread-Stainless-Screws-Fastener/dp/B07JFSWPFY 16 #10 X 2" Stainless Oval Head Phillips Wood Screws https://www.amazon.com/gp/product/B07D1LXVKJ You can use 2" wood screws to mount the Wheel Extension and then 2.5-3" wood screws to attach wheels, allowing wheel screws to go through the extension into the wood. This method was not used here but has worked so far with only 2" wood screws.
