Parametric Replicator Spool Holder - 2 (Q90535)

This is very similar to its ancestor except for a few subtle changes. I was a bit disappointed in the original in that the spool base and wall changed with the spool diameter. This required a different wall piece for every spool size. I've altered the code so that the wall piece and spool base are always a fixed size, so that any size spool part can fit on a single wall mounting. (Any size spool smaller than an MBI, that is. If there are larger spool hub sizes, a larger base would be required.) I've also beveled a few corners to make insertions easier.
