Description

This is a robust dovetail mounting system designed specifically for SBR20 linear rail sliding blocks (SBR20UU). I created this mechanism to allow for modular, quick-change attachments on linear motion projects without unscrewing the base block every time.

Key Features:

  • Quick-Swap Design: Easily slide different tools or mechanisms onto your linear rails.
  • Locking Mechanism: Includes a dedicated hole for an M3 screw. This acts as a set screw to firmly lock the dovetail plate in position, preventing sliding during operation.
  • Heavy Duty: Designed with thick walls and high infill to withstand mechanical stress.

Hardware Required

  • 4x Machine Screws: (Typically M5 or M6) to secure the base to the SBR20 block.
  • 1x M3 Screw: Used as the locking set screw (length depends on your preference, 10mm-15mm recommended).
  • If you prefer using a nut rather than threading into the plastic.
