Flashforge Adventurer 3 - Spool Holder

I couldn't find a spool holder for the Adventurer 3 I was happy with, and after testing 2 designs I decided to design my own.

It is a simple design, and slides over the exisiting spool support cylinder. While it takes 4-5 hours to print (g-code supplied), it is worth it in my opinion since it has to be reliable and just work off the bat.

I have supplied;
-STL file
-G-code file (ready to print with the adventurer 3)
-Simplify 3D 'factory' file

All feedback is appreciated. Cheers
