I realized the parent could use some different attachment methods, this one is for command strips or velcro or adhesive mag strips.

The cutouts for the default model are 0.5 mm deep x 19 mm wide, to accommodate a wide variety of possible command strips, including some of the widest command strips.

If you want to use velcro or adhesive mag strips, you may want to use the 2.0 mm deep STL version, or create your own custom version from the STEP file.

See parent for printing instructions.

In STEP (both variants in one file) and STL format (separate files).
