After searching for a fully printable spool storage system. I didn't find something that suited me. So i decided to create one fully modular.

U dont need any other items.

Im also communist so i'll let the step files for whoever wants to modify things.

*------------------------------------------------------------------------------------------------------------*

I edited the previous version so the space between floors is bigger, and now the final version is out, enjoy. U can still download the step files

There is room for 3 spool between 2 frames with the standard design 

Parts to print :

• Bars printed flat to maximise the strength of it 
• Frame that have to be used at the bottom
• Inter-Frame that can be used for structure with more than 2 lines
• Top hider, there is 2 version : 1 that allow both sides to have bar and the other that is for the sides
