You can see in the photos the exact point the print went from good to bad instantly. It did make some good prints after that though. Some of the sections of hull take a day and a half to print so this is turning into a big waste of time, filament and energy. I would appreciate anyone's experience and input. I have checked over the printer for loose belts etc. and can't find anything wrong.

Many thanks

A couple of days ago Canada determined that we're going to replace our older Victoria class submarines. They've had a bit of a checkered past, with both British and Canadian service, but a long pause and mothballing in between. The re-activation process was longer and more costly than though, and during the transit to Canada, one of the subs (HMCS Chicoutimi) had a fire onboard resulting in the death of the ship's Combat Systems Engineering Officer, Lt(N) Chris Saunders.

The submarines have had long periods of maintenance and repairs, but when deployed and operational have been absolutely among the most capable diesel electric subs in the world.

As a former SONAR Tech with the RCN, I observed sea trials and tests and can attest to them literally being a 'hole in the water' when they want to be.

I found myself with some print cycle time on my Bambu H2S, and was thinking about what Canadian Ship or Sub to putter away at in the background as I continue to work on my Type 26 project(s).

I came across the Upholder/Victoria class STL package at Nautilus Drydocks - for just under $100 (Canuck bucks), I purchased the file set and downloaded to start printing.

British Upholder - Canadian Victoria Class STL File Package | Drydocks

The files are quite detailed - the outer hull is well crafted with the Anechoic tiles showing clearly, and the 'bits' underneath them appear to be mostly in the right spots based on my rough guestimation. Torpedo tubes, flank SONAR arrays, torp loading hatch, access doors, etc, well detailed and looks really good.

A few days of printing, and I have the first sample model done. I'm a bit of a fan of doing a test print for display before doing anything that'll hit the pond, so here's what the test print looks like.

Where will this go from here?

We'll see. This is V1 - printed with Matte finish PLA to give a better 'soft rubber' look to the anechoic tiles. I think that turned out well.

I'll have the last of the parts printed tomorrow and will be assembling it to put it on display in a nearby cabinet at work.

V2 might be a 'tiny' version as a give-away in 1/144 scale for size reference.
