Summary

Disclaimer: This solution was created for my grandmother, who is visually impaired and recently broke her arm. It is designed to help improve her sense of independence.

This large-sized button is easier to handle and can be sewn on like a regular button. It features three hooks for simplified and more secure fastening. A paper clip can be sewn onto the opposite side of the garment to help with alignment.

The button should be 3D printed sideways for enhanced durability.
It does not require support, but supports can be used to improve the aesthetic finish. (Image shown: prototype printed without support.)
