So anyone have a work flow to successfully get the Standard_BigTop_SpinnerArm.STL to work correctly in Slic3r Prusa edition? Really wanted to start these overnight to have for tomorrow but I have the same problem everyone else has with missing geometry in Slic3r. If a third party tool like MeshMixer is needed, could someone lay out the steps needed to fix? Also what infill are people having success with?

Really like the way this was designed and hoping I can get one to successfully print on my MK2S.
