Inglord's excellent filament guide works fantastic as is, but I wanted to pull the filament towards the center of the roll at all times and pull it more evenly straight ahead; the wider original guides still makes the spools shift left to right as the print head travels from side to side. So, I did a very quick and simple variant of part of his excellent set. You need to print Inglord's set as well to get the frame mounts - and see if you prefer wide guides, or mine, I guess; this is a very minor change, to say the least. I printed it with a 0.4 mm nozzle, at 0.2 mm quality, using PETG.
