The spacing has been adjusted to allow the model to fit Gutermann spools and also the larger pieces resized to fit on the bed of an Ender 3.
Print six of the spool holders and two of the stands (one normal and one mirror image) and then glue together to assemble.
I added countersunk screw holes to fix the wall.
Peg Plates
V2 has four and five peg plates that are clear of the fixing holes and stagger the spools so they can be easily retrieved. You should print 3 of each peg plates to alternate each layer.
V1 has six peg plates that can be used but may foul the fixing holes.
Stands
For my V2 I've used Jason Krise's remix of the stand which includes slots rather than open shelves. I used a small amount of blu-tack in each slot to hold each plate but still have it removable.
Kevin Matthew Thomas' design is still below if you prefer the open design.
All Printed with 4 walls and 20% infill in PLA.
