A1 Mini Universal Multi Spool Holder

I designed this universal multi spool holder set for the A1 Mini. I believe that this type of spool holder is superior in every way to other spool holder designs. The friction of 6 608 bearings is just the right friction to allow smooth feeding but not too little to allow for runaway feeding when pulled too hard. It accommodates for the annoying spools with larger than standard diameter and also thicker or even larger diameter normal spools. It also prevents the filament from slipping around the holder base if there is too much slack and tangling around it which has caused me many interrupted prints. I also think that removing and inserting the spools in place is easier than a standard spool holder. This design allows 3 additional spools to be held for a total of 4 with the existing factory spool holder. You do not need to make any modifications to your printer. It simply slides on top and you're good to go. Watch the build and setup: https://youtube.com/shorts/v7gz_-OAoGU Note:I r
