Ultimate Filament Drybox Coupler Hole Jig

This Coupler Hole Jig is an enhanced version of the coupler hole jig provided with @GunplaMark's outstanding Ultimate Cereal Container Filament Drybox.  It provides a more precise drilling location for the coupler than the original version - for those of us who can't easily eye-ball the center of the cereal container used in Mark's design.

The following image shows how to use the Coupler Hole Jig:

The following photo shows the cereal container ready for insertion of the coupler:

I have provided a STEP (.stp) file to allow modifications to my design as well as an STL (.stl) file.

A PrusaSlicer 3MF file has been provided for PETG.

A G-code file has been provided for the Original Prusa MK4 for PETG.

The Coupler Hole Jig seen in the photos was printed with Sunlu Gray PETG with a 0.4mm nozzle at 0.2mm layer height.  Supports are not needed.
