Adjustments to Solidworks model

I have an existing model done in Solidworks for a 3D printed joystick-style controller. I am making some changes to the design and have these sketched on photos attached. I have also included some technical drawings for other components which attach to it to provide details of spacing for screw holes etc.
The changes are as follows:
- Remodel of upper section for new thumbstick gimbal
- Move Hole at bottom (for output wires) to new position
- Replace previous mounting pins for circuit board with the sketched bracket
- Match changes to opposite half of joystick

Is this something you could do? I just need the Stl for 3D printing, not any rendering

Thanks in advance for your response,
Will
