Printed perfectly without supports using designer's settings (PLA, .2 layer) on a textured PEI plate. Was immediately movable with just a tiny amount of force to break free initially. Really well designed! Also, fits around the carbon rods very well. When taking it off, may collide with the belt if not careful. But that's okay and not a problem. It even would hold in place without springs for that reason. (can't rate because I printed multiple different models on the same plate, but obviously 5 stars)
