IKEA POÄNG feet

prusaprinters

<p>Do you find your Roomba frequently getting stuck as it tries to mount the feet of your your POÄNG chairs? Don't want to ruin the clean aesthetic of these bouncy sitting devices? Have a 3D printer and want to use it to achieve something practical other than printing endless boats?&nbsp;</p><p>Try these! &nbsp;All you need extra is a standard self-tapping countersunk wood screw to go through the centre.</p><p>Screw these feet into the underside of your<strong> </strong>POÄNG<strong> </strong>chair - 4 to maintain stability. They're <i>just </i>high enough that the bump sensor on most robot vacuum cleaners will collide with it and make them avoid the feet rather than trying to mount them - but short enough that you can barely see them from above.&nbsp;</p><p>Sometimes if you have carpet and it's especially squashy they might be just a little too short. Scale them up vertically by a few % and they should still just about work.&nbsp;</p><p>For hard floors, it's recommend to print in a flexible filament, like <strong>TPU-95A</strong>.&nbsp;</p><p>For carpet, pretty much anything works fine - PLA, PETG etc. You may wish to slice off the rounded top if you find the layer lines catch on your carpet.&nbsp;</p>
