Kate Reed and Nathaniel Tong created the Hand Drive wheelchair attachment, a hack which serves as an answer to the expensive, lever-powered wheelchairs they saw that retailed anywhere from $2,000 to $10,000. The pair say that, rather than take on the task of completely redesigning the wheelchair, they sought to make such lever-powered wheelchairs more accessible to everyday users. Their solution is almost entirely 3D printable - and costs only $40 to make. The Hand Drive wheelchair attachment can be adapted to any wheelchair and lets the user make a rowing motion to bring the larger muscle groups into play.
