I was not content with any of the filament guides aligners I did find. None of the seem to really do the job. That's why I took two of the ones I liked most and combined them into one. Since I use this one I do not get any breaks even if I use a 2kg roll
I printed the (1) with support, just to be sure, but it can be done without.
I printed all with 3 outer layers (top bottom and sides)
Just print and put together. I used some superglue between 1 & 2, but this is not necessary.
One warning. The holder (file (2)) and the roll snap together really tough, watch out you don't break one or the other. The rimm on (2) is needed to keep the roller on.
