This design aims to be simple, and reliable. Other mounting options are coming, so consider this a work in progress. I'm still playing around with solid and hollow body options, and will need to add variants for different drive gear diameters. The built-in tension spring will probably become a removable/swapable feature very soon.Features- No springs to adjust (It's not a bug, it's a feature!)- Compact- Reversible, for side-by-side dual extruder use- Cleaning port for easy clean out- Fully guided filament path, for easy loading
