17mm pipe / tube holder for filament box

This is a bracket / holder to hold a pipe / tube for a 3d printer filament spool. I am using these in a large plastic container to keep my filament from absorbing too much moisture.

I made this to be used with M5 or similarly sized screws. I have included the freecad File so you can modify this design to your needs or follow along in my FreeCAD tutorial! :)

Check out the FreeCAD tutorial where I show you how to design this and 2 other parts for 3D Printers:
