KALLAX No-Wobble Support

When assembling my IKEA KALLAX unit with the original leg/base accessory, I noticed that the support system has a lot of unwanted play.Once mounted, the legs felt too loose, making the whole structure move and wobble more than it should. Although IKEA refers to everything simply as KALLAX, this issue comes specifically from the leg/support structure that is mounted underneath the unit. Instead of accepting this, I designed this simple support fix to remove the clearance in the original design.This part eliminates the play, locks the legs firmly in place, and makes the KALLAX feel much more solid and stable once assembled.The model is designed to fit snugly inside the original leg/support structure, acting as a tightening insert/spacer.It is very easy to print, does not require any supports, and works well on standard FDM printers.To install it, simply replace the original round plastic pieces included with the KALLAX leg accessory with these printed ones.No modifications to the furnitu
