Two Trees Bluer Spool Holder

This is my first design, I cant seem to find any decent spool holders for my Two Trees Bluer printer that I am happy with.
I basically started from the ground up with a design based on the Anet A8 spool holder which is one side as opposed to on top of the printer, a piece of 8mm Threadbar with M8 nuts will act as the Axle, you will have to also download and print the "Ultimate Spool Adapter" set.

Its designed to fit over the Ender 3 "V5 More Rigid Mount 2020 Ender 3 Filament Guide"

The bolts designed to be used are m4 x 12mm into the original locking nuts that the printers spool holder comes with.

I also added external supports for the holder which I am hoping will support the spool's weight, but again it is a work in progress so I will have to see how it goes. Pi
