Multi-purpose ergonomic handle grip

pinshape

This design was born from a young girl's struggle with cerebral palsy who consistently struggled to grasp her deodorant in the right spot. To overcome this challenge, we created a handle that clips onto the bottle and provides a firmer hold while accommodating her limited wrist mobility. Once our handle was complete, we realized its potential went far beyond assisting individuals like her - it could be adapted for various tasks yet to be discovered. To build the handle, you'll need: A 3D printed collection of parts, including a handle, left clip, right clip, and tri-knob. An M5 nut and bolt approximately 50mm long. A 5mm dowel rod. A small spring that fits snugly over the dowel. Epoxy resin for bonding. M5 wood screws, one approximately 10mm long and another about 30mm long. With epoxy resin, secure the M5 nut into the left clip's hole. Then, bond the head of the nut firmly to the tri-knob. Next, join the left clip to the handle using the longer wood screw. Insert the dowel and spring into the left clip as shown in the image. Finally, insert the bolt into the nut, tighten it, and connect the two halves of the clip together. If you need extra grip for smaller objects, consider using foam or cardboard packing.
