In looking for a vertical socket storage for my Tekton 3/8 set I couldn't find anything that had all the spaces for my set and no extras so I made it myself. The pieces are designed to be printed on an Ender 3 bed size (the 6-15mm will need to be rotated a bit). The pieces were designed to be able to glue together with maximum surface area available if you only want a single organizer but mine stay put in the tool box just from the weight of the sockets so no glue needed.

This includes the full SAE and Metric set from Tekton

Feel free to remix if it suits you better.

Hopefully this helps someone else. If you make one please post it!
