because the space is not never enough I made storage box for Keter workbench to storage some parts when you working on your projects. boxes are removable.
to complete I used super glue, M5 nuts and M5x12 (DIN934).
nuts I preheated and inserted into the holder. to be sure, I secure them by glue.
it is up to you, what you use for printing. I used PLA, standard setup. for table inserts I used supports.
enjoy and share it :-)
