This is a 3D model made using OpenSCAD for a Topre key. Dimensions for rows E, D, C and B are available in the file or in STL renders. The dimensions were made using a caliper and based on a HHKB. The code is also available on Github at the repo: https://github.com/fernandodeperto/topre_key Feel free to make comments or suggestions. Also, issues can be open at Github.
