- The model is suitable for ender3, please set the scale of the [model](https://cdn.thingiverse.com/assets/58/5d/85/3f/a8/Low.stl) to 50%-56% of the original
- Don't set the pullback value too high, Groot will be very uncomfortable :(
- Since the original [model](https://www.thingiverse.com/thing:478806) cannot be submitted for remix, only the base model can be submitted here.
