I remixed this part because I purchased a refurbished Sermoon D1 and the machine did not come with a filament guide. Apparently the original design wasn't very good so Creality eliminated it. I found a filament guide created by TechnologyQuiet (https://www.thingiverse.com/thing:5197161) and mixed that with the original frame mount. The mix is printing as I write this so I cannot post any results yet. I will update after testing.
