I have some 3kg spools that are a bit wider than normal spools that would not fit on the stock spool holder. There are a bunch of spool adapters that are great but I just needed something simple.
This spacer extends the stock spool holder out another 4.5mm to accommodate larger and wider spools. It can be printed in whatever material (I used PLA). Just remove the rod where the spools rests by unscrewing it. Will need to hold the rod where it is flat for a wrench to hold. Then put it back with the spacer in between. Still plenty of threads to hold it securely.
