Foam of desired density (I’m using a foam football that was perfect)
Large bread knife
Small paring or steak knife
Small stick/toothpick (I used a small Alen Key)
Individual A (person for who i made the tool):
Can’t grasp a pencil/pen
Can loosely grasp a large marker
Can (due to resistance in hand function and foam density) hold a soft rubber/foam ball
Depending on a persons degree of ability the ball can be made with different foam densities. I chose a medium soft foam for the individual after having them test it out.
Also pictured are my original sketches.
Step 1: Measure & Divide
I then marked the 3 inches onto the index card and made a 3x3 square.
I cut the football in half between the middle to laces, I sawed with the bread knife.
Step 2: Cut
Now I cut along the squares lines towards the point of the football, as straight as I could. I came out with an angled rectangle.
I then placed the 3x3 card on the rectangle, starting at the front where we first cut our football in half, and traced another square. I cut off the end of the football.
Step 3: From 'Square' to Sphere
I took the misshapen sphere to the person I was making it for to see how well it fit in their hand. I checked to see if it was still too large or too small. It was a good fit, I took note of how and where their fingers grasped it. The person has two contracted fingers with very limited movement and the ball pushed outwards on them.
Step 4: Making It Personal
Step 5: Fitting the Pen
I then inserted a pen (bottom side first) and slowly pushed it in until it pressed onto the other side of the ball where I made another X cut to let it slide through. The pen is now firmly secured into the ball and can be used with much force and not move it out.
Step 6: Write With Confidence!
I did all the modeling, not the individual for whom it was made.
