This is a 4 part design - one big body and 3 snap in springs to hold the reel in place.
I was having trouble with the other designs because the reels are in various tolerances and it either go hard or too easy and I had to use masking tape to tighten them.
So this uses springs to hold the reel in place.
Printing the springs adds only a few minutes to the overall print. Remember you need 3 of them.
