Filament Guide for Creality3D Ender-2

To mount the spool holder in the front, you'll want a design like this to balance the printer's center of gravity. Otherwise, the filament will get dragged from the side and is much more likely to tangle up. I printed mine with 100% PETG infill, which was maybe overkill but gave me extra stability peace of mind. Supports were needed for this print. To make it easier, I rotated the design 90° in the slicer so that the flat surface is at the bottom, and used support material to speed up the print time. You'll also want a bearing bushing or similar thing to prevent the filament from rubbing against the oily threaded rod: https://www.thingiverse.com/thing:2186253
