I was replacing my print of the original Type 1 Spool holder. I find this version a little more difficult to get the covers on. The 'not round' covers seem to hang up more often. I DO like the windows in the Type 2 holder. I did manage to put some of the numbers on the outside upside down, but that is really a me problem and nothing to do with the model itself.

Had some difficulty getting the stays to slide into the holder once a sheet was in place. Have not found a good solution yet, but work is ongoing
