Ship Remix - ballast compartment

thingiverse

I've made some adjustments 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. Any equivalent penny coin in your country might be a slightly different diameter, but you can still 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 its equivalent in your favorite slicer) to pause a few layers 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 prevent it from rattling. I created this by importing into Tinkercad and positioning two correctly sized negative space cylinders in the center of the model. I had to reduce the polygon count in Mesh Lab to make it import okay, which didn't seem to have impacted the print quality. Thank you for the original upload, it's a great model!
