3D Model: A 3D-rendered Image Of A Compact Plastic Card Holder Designed To Attach Directly To The Arm Of An SG90 Servo Motor. The Holder Has A Simple Rectangular Clamp Or Clip Mechanism To Securely Hold A Standard Credit Card (85.60 Mm × 53.98 Mm) Vertically. The Attachment Point Fits Tightly Onto The Servo Horn (cross-shaped Or Straight) Using Screw Holes Or A Slot. The Design Is Minimalistic, With Clean 90° Angles And No Unnecessary Elements. The Focus Is On Functionality: The Servo Should Be Able To Move The Card Precisely To Simulate A Tap Gesture.
