ShelfAlign — Indexing Drill Guide

Created today

Description

Get perfectly spaced, straight shelf pin holes in any cabinet carcass with ShelfAlign. Designed for continuous drilling, this guide allows cabinet makers and DIYers to easily expand shelving layouts. The built-in indexing peg locks into the previously drilled hole to ensure infinite, perfectly aligned runs, while the integrated edge fence sets the perfect setback distance every time.

Features

  • Continuous Indexing: A built-in placement peg on the underside allows for seamless, perfectly spaced chains of holes over any length.
  • Standard Spacing: Precision-placed guide holes at the industry-standard 1 1/4" (31.75mm) cabinet intervals.
  • Edge Alignment: The integrated side fence automatically maintains a consistent setback from the cabinet edge.
  • Ready for Expansion: At 300mm long, it covers substantial ground while remaining easy to print and handle.

Print Notes

  • Print flat on the build plate for the best layer adhesion and dimensional accuracy.
  • Use a minimum of 3 to 4 wall perimeters. The extra walls help the drill guide holes resist wear from the flutes of the drill bit.
  • Tougher materials like PETG, ABS, or ABS-like resins are recommended for longevity, though PLA works fine for one-off projects.
