It’s stable when placed on the bed or floor and is ideal for relaxing the legs, lower back, and other muscle groups.The structure is simple, easy to print and carry—great for everyday use.Recommended Print Settings:Material: ABSNo supports neededInfill: 20%–30%Layer height: 0.2mmFeel free to download, print, and share your feedback or suggestions!
