This thing will fix the cheap spool holder made by anycubic for the new kobra series. When you put a new spool the much weight will bend the holder and in matter of few months it may get broken. Also the weight of the spool create a misalignment of the spool resulting in various problems. Print this and apply in the other side of the spool holder, it will keep it aligned and fully functional.

No supports no brim just print. DO NOT SCALE/RESIZE OR IT WON'T FIT, PRINT IT AS IS.

You can print it in pla, i did in petg it is the same. i use gyroid infill at 30% but change it as you like.
