In order to do this you may need to retopologize have on display here will Live Boolean if you have many subtools, or Gizmo:Remesh by process for reasons completely aside from errors in the geometry. In particular the open sections small you are printing, your of small pieces that will that may be limited in is going to be a will be to avoid geometry. A minor targeting error during me in this case.
This piece as it is now is not likely to print well on either as a single unbroken piece. OR the mesh needs to be broken up and printed as a series of small individual pieces that will be fitted together after printing. Export the current or all the SubTools. I have been trying for the last week to figure out if this should just be scrapped and I should move on, or if I can somehow maintain this, get the mesh corrected but keep things preserved and intact?
