First of all, thanks to @Costopher for his work here.
But i decided, that i need to have more/smaller containers/drawers per spool.
I remixed/resized the files of him and created some connectors by myself.
If you like my remix, please give @Costopher also a like/rating!
If you have any problem or suggestions for improvement, just leave me a comment. :)
For Printing:
Containers/dividers can be printed with PLA, but i suggest to print the connectors with PETG, since most PLA filamets are to brittle and break if you screw n the screws!
For assembly:
Just print the conntainers/drawers and some connectors. I used some M2.5x6-12 / M3x6-12 screws to connect the pieces together.
