Open Hardware LCD Controller Knob

thingiverse

This is a remake of the Open Hardware thumbscrew model # 121099. I loved the design and the logo, but I needed a knob instead of a thumbscrew, so I imported the STL file into OpenSCAD and remixed it myself. I'm using these knobs for my 3D printers' LCD Controller rotary encoders, and they fit snugly on the 6mm split shafts - you might need to scale them up by 1 or 2% in your slicing software if they're too tight. I've included both the OpenSCAD source code and the original STL file so you can remix this design further. These knobs work great when printed with the open hardware logo facing up, but it's also fine to have it face down - it's all about personal preference! For my PLA prints with 35% infill, I got a really nice result.
