Filastruder Vertical Bottle hopper deep throat version ;-)

thingiverse

I really like this design but after reevaluating it I realized that the throat was narrower at the bottle end and decided I wanted it to be the same width all the way down - making the modification resulted in the end just under the bottle being a little deeper. I also widened it very slightly and added a thread, allowing me to use 1.5L PET water bottles instead of gasified drinks plastic bottles because they seem to have a different thread... Finally, I reduced the number of M4 screws from six to four as I found it was a pain to have so many, and the part started to break at the layer of screw heads possibly due to excessive force - with fewer screws less force is required, and the hopper only needs to be tightened enough not to move. It's designed for Filabot V2.1 with acrylic panels. You can download the design from the Fusion360 gallery page in any format that Fusion allows if you want to make changes; https://a360.co/2JsWgHp Remember always to cover the hole or bottle when not in use, dust is the enemy of good extrusion!
