Office Chair Feet - Customizable (fusion 360)

thingiverse

I aimed to achieve two objectives: firstly, to lower the chair since the lowest setting with the wheels is still too high for me; secondly, to use the chair on wooden floors without causing them damage. This design is tailored specifically for an Ikea Markus chair, but I've included a .f3d and a .step file so you can adjust the parameters to suit your office chair as well. You may need Fusion 360 to edit these files. Initially, I considered purchasing rubber to attach to the bottom of the feet, but a more cost-effective option was to cut up an old rug and use it as a floor protector. The feet are held in place by friction, so if I pick up the chair they won't fall out. The combined weight of the chair plus myself is approximately 20kg+70kg=90kg, evenly distributed across 5 feet.
