Update 2/2/24
Added Extra profile containing optional underwater parts and a stand - which can be bolted on the bottom with 3xM4 x 15mm Cap head screws.
Update 13/2/24
Updated the underwater print profile to move the section breaks so that they line up with the main waterline model.
Also doubled up the tiny azipod motor parts - as it doesn't add much to print time and will then give some spares in case of breakages or printing issues.
Also slightly improved the adaptive layer height settings.
Update 4/1/24.
I have added the underwater hull part of this ship to my 1:1000 scale version here
https://makerworld.com/en/models/15006#profileId-14776
If there is any interest in a version scaled for this 1:500 version please let me know via the comments I will create one.
Scaled at 1:500 and mutli coloured - this model is multi plate, quite large and requires a lot of time to print.
It is recommened that people try one of the 1:1000 or 1:1250 version first - which print without supports on a single plate.
Updated 31/12/23
New version of the Dome on deck18 added as a 2nd + 3rd plate on the same print profile as was uploaded on 21/12
Updated 21/12/23
Alternative version of deck 8 included in seperate profile - to avoid issues with lighting channel showing through very thin deck layer.
Updated 9/10/23:
Corrected a problem with a duplicate part from deck 15 being present and one part from deck 14 being missing.
See Plate 14.
Updated 30/9/23:
Corrected a problem with the port side of the hull section not slicing correctly.
Also note that since releasing these complex multi part 1:500 ship models I have found that the BL printers are capable of printing these models quite well at a 1:1000 scale on a single plate. Seperate entries in Makerworld have been created for the 1:1000 versions.
Update: 8/9/23:
A new version of the model has just been updated that addresses points 2,3,4 & 5 below.
Update: 18/8/23
Following feedback from the 2 successful end user prints of this model I am planning to make the following updates:
Third ship in a series of Seven 1:500 scale Models of P&O Cruise Ships - Iona - for personal use only.
Iona is the largest P&O Cruise Ship currently in service.
Designed for multi colour printing on a Bambu Lab X1C or P1P with 8 Colours (2 x AMS).
STL files not available individually as there are too many.
Designed using Fusion 360.
Model is approximately 3 build plates long - so needs to be printed in separate sections which are slotted together at deck level, then each deck is bolted together using M4 Cap Head Screws.
Printing will take well over 60 hrs in total - in separate plates which average about 2 hrs printing time each - but some of the more complicated plates take in excess of 13 hours to print.
For reference here are the filament colours I have been using in order of quantity - with a best guess at Bambu Lab equivalents
eSUN PLA+ Filament 1.75mm, PLA Plus 3D Printer Filament Cold White
eSUN PLA+ Silver
SunLU PLA+ Blue
SunLU PLA Red
1kg 1.75mm PLA 3D printer filament Printer - With coil (Gold Color)
SUNLU 3D Printer Filament PLA+ Plus Grass Green
Aldi Balco Blue 1kg
SunLU PLA Yellow
Bambu Lab Orange
ICE Filaments ICEFIL1PLA104 PLA filament, 1.75mm, 0.75 kg, Barbaric Brown
eSUN PLA BLACK
With the quantity of white being about 10x the rest.
My best guess at equivalent Bambu Lab Filaments to these would be:
Bambu Lab PLA Basic Jade White
Bambu Lab PLA Silk Silver
Bambu Lab PLA Basic Blue
Bambu Lab PLA Basic Red
Bambu Lab PLA Basic Bronze
Bambu Lab PLA Basic Green
Bambu Lab PLA Matt Ice Blue
Bambu Lab PLA Basic Yellow
Bambu Lab PLA Basic Orange
Bambu Lab PLA Basic Brown
Bambu Lab PLA Basic Black
Around 22 M4x16 and 4 M4 x 10
Build instructions. (updated 18/8/23)
Model has only been printed once so far, and was re-sliced for this upload.
Further details of the design and built process are available on the Bambu Labs forum AMS section.
Details of this model will also be posted on
This is a personal project. I have no connection to P&O Cruises or Carnival Corporation other than being a customer.
This version is released under a CC Non Commercial No Derivatives license due the P&O Cruises branding.
