I made this project for my filament spool holder needs that I wanted to share with you in case it could be useful.

The material used is PETG, but feel free to use other materials, for greater resistance and I also included several accessories that fit perfectly.

NB: I bought the tubes used in a Brico and they are in white painted metal (there are also other colors) and as a diameter they are 20 mm.

I made hooks for various materials, as well as a tape holder, an accessory shelf and hooks to store FPV drones.

NB: I will upload various profiles for the accessories used to make it easier to choose.

FOR THE ASSEMBLY: I did not use glue but only joints and the screws used to fix the two inserts to the shelf are 6 while for the wall brackets I used screws with 8 dowels.

This is the final result and I'm happy with it.
