Larger connectors for Hanging Spool Holder with PTFE tube holder

The original is a tight fit (kudos to the designer!). I found that when I assembled it, the round side wheels ("interface") rubbed against the legs. To give it a little more room, I modified the “connector” pieces (the horizontal bars that go between the legs). I made each one 2mm longer, without scaling any of the other measurements. Now there's a little wiggle room.
