Description

Lee Precision Bench Plate Mount — Product Summary

Description
Bench-plate mount designed for Lee Precision presses with an integrated keyed pattern for the RCBS 9460 primer tool. The pattern is editable in your slicer to fit other primer tools or reloading accessories. Intended primarily for pistol-size presses; may work with small-rifle setups but no guarantee. Larger rifle shells or heavy presses may exceed PLA’s mechanical limits.

Key Features

  • Fits Lee-style bench plate mounting pattern
  • RCBS 9460 primer tool recess included (modifiable)
  • Slicer-editable for other tools or minor adjustments
  • Optimized for pistol-size cartridges

Limitations / Notes

  • No guarantee of fit — verify dimensions prior to final prints.
  • Small-rifle compatibility is uncertain; larger shells may stress PLA.
  • Consider stronger filament (PETG/ABS) or reinforcement for heavy loads.

Printing Recommendations

  • Material: PLA (easy print), or PETG/ABS for greater toughness/heat resistance
  • Layer height: 0.16–0.24 mm
  • Infill: 30–50% (higher for strength)
  • Perimeters: 3–4 walls
  • Orientation: mount face down on bed for accurate hole/bolt tolerances
  • Post-print: verify bolt holes; consider drilling/tapping or using metal inserts for long-term durability

Safety / Disclaimer
Use at your own risk. Inspect fit and structural integrity before applying load. This is a DIY accessory — not OEM — and carries no manufacturer warranty.
