This is a quick-adjustable straight edge guide using a switchable magnet. Multiple magnets can be used, but 1 in the center is sufficient. The magnet can be fastened to the guide with M5 screws if needed.

6mm OD x 12 mm L pins may be used to chain these together for a longer reference edge.  

The part will fit on a Bambu X1C.

Print Recommendations:

  • No supports
  • Use a high number of wall loops for increased strength
  • Use ~35% infill for increased strength

I use this to align parts on a lasercutter, but it will work on any magnetic surface.

Instructions to use:

  1. Ensure the magnet is off
  2. Place the magnet(s) in the slot
  3. Place the guide on a honeycomb steel bed and adjust to the desired position
  4. Turn the magnet(s) on
  5. Push your part against the edge guide to locate it.

Additional Notes:

  • These magnets are very strong
  • Do not laser printed plastics or the magnet
  • The outer dimensional tolerances for the magnet are poor; this design should fit without issue but MMC magnets may need some force to push in
