IKEA Vimle leg extension

Basic Leg extender for a IKEA Vimle sofa, that allows autonomous vacuum cleaners such as Roomba or Roborock to drive and clean under it. I tried to preserve the original shape of the rounded edges, the hole in the centre is to allow pushing the screw if it drops during mounting. Things to know before printing:I recommend to insert the original 6.5cm leg to the extender before screwing it in the sofa (otherwise it can crack if you accidentally drop the sofa on it)This extender creates ~11cm space from the ground to the sofa edges, and hides flush with the leg top surface - check if your vacuum cleaner is not taller than this.The inner nut serves as a lock to hide the seam on the inner side of the sofa - to hide the seam it'll require sliding the extender off by ~5mm before rotating itPlease check how many legs are on your sofa & multiply the model accordinglyAs this is my first 3D print model I'll be grateful for any type of feedback on the print. Printed in ABS as it uses less
