The smaller part is to a 0.2mm tolerance or no tolerance. I've not yet printed it, but hope it works! If you have any questions please feel free to ask me! Print notes: Walls: To create a strong part, it is advised to increase wall thickness. Supports: Only needs support for embedded nuts, but may be fine without. Orientation: print hotend clamp standing up and X-carriage with hotend clamp notch facing upward to minimize support. Infill: 40% or more for a strong part. Time: MyMiniFactory took 3 hours 50 mins to print all parts.
