Ship Remix - ballast compartment

I have made a minor edit to incorporate two sealed chambers low down within the hull that is specifically designed to accept a stack of British pennies, which act as ballast to help stability when floating.

The model has been scaled up to 160% to make maximum use of my 150x160mm build area. Obviously the equivalent penny coin in your country might be a slightly different diameter, but regardless you can use old nuts/bolts/fishing weights/etc. The chamber is 21.5mm in diameter and 24mm tall and ends up sealed within the model.

Instructions: Slice the model, then use the preview mode to find at which layer the top of the ballast compartment is printed. Use the post-processing plugin (in Cura, or the equivalent in your favourite slicer) to pause a few layer below this and reslice.

When your printer pauses mid-print, fill the chamber with ballast then hit continue to seal the chamber. You might prefer to put some glue around the ballast material to help stop it rattling.

I created this by importing into Tinkercad and positioning two correctly sized negative space cylinders in the centre of the model. I had to reduce the polygon count in Mesh Lab to make it import okay, which doesn't seem to have impacted the print quality.

Thank you for the original upload, it's a great model!
