Lee Precision Pro Auto Disc Blank

thingiverse

This disc features two holes, measuring 4mm in diameter and can be enlarged to suit specific requirements through drilling. The model utilizes four perimeter shells; however, users may need to increase the number of perimeters or set infill to 100% if larger holes are desired, ensuring a maximum hole size of approximately 0.5 inches. A slight sanding process is required to ensure a proper seal without leakage issues. Moreover, the design is intentionally constructed at a thickness of 0.5mm greater than OEM discs, accounting for potential printing errors that may impact fitment.
