Simple, quick and easy to print ( no support) , and very efficient !
It is the V2 , this one is for Tower Drying rang with crossing legs, and for legs with flat profile ( V1 was for legs with circle profile).
This version is 23mm large ( legs) and 10mm height ( between floor and legs).
I guess it is resizable in Bambu Studio to adapt to your Tower Rack but feel free to ask other versions.
