Stress-Relief

Stress-Relief 3D Model (STL) for Bambu A1A ready-to-print STL file has been created for a simple, support-free stress-relief roller:What the model isThe STL is a one-piece cylindrical roller designed to be:Held between fingers and rolled back and forth.Used as a fidget / stress-relief tool.Easy to print on a Bambu A1 without supports.Basic geometryShape: Cylinder with textured ridge rings along its length for extra grip and tactile feedback.Length: 60 mmBase radius: 10 mmRidge height: +1 mm over base radiusRidges: Evenly spaced along the length; each ridge is a narrow ring.This prints cleanly in PLA, PETG, or TPU. For a softer, more “stress-ball-like” feel, TPU is ideal; for a standard hard fidget, PLA/PETG is fine.Print recommendations (Bambu A1)Orientation:Import the STL and print it standing upright (cylinder axis vertical) or lying on its side; both will work without supports due to the smooth cylindrical profile.Layer height: 0.2 mm for a good balance of speed and detail.Infill: 1
