Here is my go at having my tool box organized. this is the single socket holder version that uses ¼ aluminum rod from home depot that you cut to what ever length you want. make quick on the go sets or 3ft long sets. the option is yours to choose. 

these double socket holders are not interchangeable with each other size. so ¼ set pieces wont fit with 3/8 pieces. 

I used this metal rod from home depot - [https://www.homedepot.com/p/Everbilt-1-4-in-x-4-ft-Aluminum-Solid-Round-Rod-6006/332734330](https://www.homedepot.com/p/Everbilt-1-4-in-x-4-ft-Aluminum-Solid-Round-Rod-6006/332734330)

May need to scale up or down by 1% depending on your printer and material. i used PLA and have been over a year with no issues.
