Filament Guide Wheel for Dremel 3D45

thingiverse

I think modifying the original design by les_kaye was a clever move. By attaching it using the 2 screws at the top of the extruder and ditching the double side tape, you managed to simplify things significantly. Replacing the M3 screws with longer ones (M3 x 20mm long) was a great idea, as it provided a more secure hold. To keep the wheel in place, I used an M3 screw that's 25 mm long with a nylon lock nut on the other side. For those thick marks, a quick coat of red sharpie did the trick. The original wheel design remains untouched - I only tweaked the holder to fit my needs. One thing that caught my eye was the size of the wheel; I think it would be better suited with a slightly smaller diameter, but we'll see how that pans out later on.
