ikea alex desk leg extension

My Ikea alex desk needed to me little higher for my new gamingchair
so i made this extension about 4cm higher plus 1cm addon if want more.
it slides right on the legs
Wanted it to be strong but also dont use to mutch filament
printed it whit 40% infill pla 200c 50c bed
strong hold but it can be better will update later on .if there is any issues i fix it

edit: will update when i have all 4 printed and mounted dont want any desks to fall over out there, =) will check the strenght
