Spool holder (Blueprint3d edition)

Note: I have added a revised version that is stronger and uses less material (now 156grams)!

This is my filament holder which I made for my cube 3.
I am working at present on how to use an external spool on the cube 3.
So I will need this.

Blueprint3d is my filament supplier who has been a great supporter of my projects, including sponsoring my 3D printed wheelchair.

SO I will also link this to his facebook group so they can all get one...if they want :-)
