Notes

  • Block envelopes with the rail channel at the exact rail section. The block's underside sits H1 above the rail bottom (MGN9 2.0, MGN12 3.0, MGN15 4.0), so the file's block height is H − H1: 8, 10, 12.
  • Assembled height H from the rail bottom: MGN9 10, MGN12 13, MGN15 16.
  • Four M3 holes, drawn at Ø3 (thread major), across × along the rail: MGN9H 15 × 16, MGN9C 15 × 10, MGN12H 20 × 20, MGN12C 20 × 15, MGN15H 25 × 25.
  • C is the short block, H the long one; same width and height.
