SquigglesTube Caliburn

I modified the Ryan tube and TopRail to further minimize wobble. My print came out at 99% for a snug part-to-part fit, but 98% might have been even better. Be aware that the nubs also scale, so find a balance to make them snug. The optimal setting will vary depending on your printer's tolerances. I likely need to flip these in my slicer so they can be printed without supports, as they would be properly oriented in the original Caliburn files.
