Wheelchair Joystick Cover

I used the measurements of the face of the joystick to create an object that would cover the buttons. I combined a square and circle to make the shape rounded at the top with a length of 4 inches, width of 3 inches, and height of 1 inch. I then went back to make the width 3.25 to allow for space for velcros on the sides. I duplicated this shape and extended all the sides by 0.25, except for the bottom, which would be open based on the joystick design. I aligned the two shapes at the bottom and cut out the smaller one from the bigger one to make a hollow shell that is 0.25 inches thick. I will bring this design to the client to see if it fits correctly and make adjustments as needed. Update: measurements fit perfectly and no changes were made.
