This is a "SPECTRUM" spool organizer Dimensions of the clear opening - 53mm x 47mm.
1 piecе "L" drawer+5 dividers+1 bottom pin.
2 pieces "M" drawer+10 dividers+1 bottom pin.

I've been looking for quite a few such models, but I couldn't find a "SPECTRUM" type reel, so I borrowed some ideas from other models and created this model. I will be happy to be useful to anyone in need.

They have been added base and bearing between the spools.
