3D printed 1/72nd Columbia class submarine

[RCjetdude]

This is my 3D printed Columbia class sub (SSBN-826) measuring in at 93" long with a 7-1/8" beam. Based solely on artists conceptual drawings as they just started building the first boat back in October.. Completely printed with ASA filament on my Ender 3 Pro. It is ready to split the hull and start working on the running gear. Nothing fancy. It is too cold to put a coat of primer on it and needs a few things done inside first. This was my first full CAD project using Fusion 360 and could still use some tweaks but it turned out well. Taught me a lot in the process but something I did over my Christmas break. It took 4 spools of filament and just over 3 weeks to print. I still need to design some interior bulkheads but they should be easy. Altogether I estimate I will have about $500 in this one. Will be using the water tight enclosure and power module from my Ohio in it. Always good to share components when possible.

It didn't take long to cut the sides with a razor saw and split the hull.

It now has a coat of primer and looking very good. Getting close to being finished.

[RCjetdude]

Getting very close to being done. Lights installed. Down to some final wiring and radio setup.

And today she had a perfectly trimmed hands off periscope depth run.
