Designed these to mount SAE and Metric sets of Pittsburgh hex key sets.  Holds the set as whole in the original holder they came with.

Has push fit connectors to use with snaps.  I used the moderate weight bearing snaps found here ----> https://thangs.com/designer/MultiBuild/3d-model/Raised%20Moderate%20Weight-Bearing%20Snap-989145

Printed with 3 walls and 15% infill -no supports.
