Gridfinity Numpad numberpad Epomaker ek21

I slightly modified the original model to better fit the standard Epomaker EK21 layout.
I believe the original design was based on the EK21-X variant, which appears to be slightly larger, so I tightened some dimensions and adjusted a few parts to achieve a more precise fit.

The numpad now fits perfectly and feels much more secure inside the bin.

Additional changes:

• Added a dedicated slot for the USB dongle
• Added the object name on the model for easier identification
  (If you prefer a cleaner look, you can simply remove the text object from the Blender/Object list before exporting.)

Thanks to the original creator for the great base model!
