To begin modelling the handle, I extruded regions of the outline out from the midplane. I started with the outline and midplane of the mesh: I used Autodesk Inventor because I knew how to use it and the Mesh Enabler extension was free at the time. We need a solid model, not a mesh, to modify the handle and 3D print it. ![]() Overall, the scanner did a good job. Most of the surfaces were smooth. I spray painted the handle matte gray then used TechShop’s NextEngine 3D scanner:Īfter aligning scans and some correction in NextEngine’s software, I got this mesh: I did not end up making a longer handle because of time constraints, and then I got a new bike. In 2013, set out to make longer brake handles with a TechShop membership. The cable-pull levers (example at right) were easy to disassemble, so I 3D scanned the old handle and reverse-engineered a solid model. This was very slightly inconvenient so I looked into doing something about it. ![]() When my hands were on the bar ends on my old mountain bike, I couldn’t reach the brake handles.
