Key style filament guides for the Geeetech Acrylic Prusa i3

cults3d

The edges of the display board of the Geetech acrylic Prusa i3 are rather sharp and filament fed from behind the printer tends to rub against them or even get pulled in the corner the display board and the main upper bridge forms. So I designed a few things that are supposed to make the filament run over that edge more smoothly. The first variant is closed, so you need to slice it open or ensure to have the filament run through it when loading. The second (Key2) is sliced in half on the clip-on side to allow for inserting the filament. The third (Key4) has on opening hook mechanism at the front. Best for me so far.
