About this 3D model
This is the belt tensioner for the Felix 2 printer that is for the GT2 pitch belt conversion. The Felix 2 comes with 3M timing belt, but I couldn't source locally when I had problems, so converted to a GT2 2mm pitch belt. You can use the same part for both X and Y Axis UPDATE: I mistakenly uploaded an earlier version of the STL where the belt was a bit slack, the current version is the correct one
