1/72 Seaview by Ken Lane

[TAGood827]

I'm working on the Ken Lane designed 1/72 Seaview 3D print files offered by Nautilus Drydocks. I'm hoping to hear if any others on the forum are tackling this project as well. I'd like to share ideas and problems encountered during your build.

I'll offer first that after I bought the file set, I began evaluating material required. I began with the lower hull sections and laid them out in Orca Slicer for use with my Prusa XL. The original design has several horizontal ribs requiring support in the printing of each section. This results in a substantial waste of filament to produce each part. I decided to modify the files to add a 45° chamfer under these ribs and the top joiner rib to eliminate the need for support. I have completed hull sections D through I so far.

I also created a complementary chamfer piece to fit next to the chamfer under the top rib so there was a flat clamping surface to join the two sections. As there is no official manual for this model that I am aware of, I wasn't sure if the plane was to use self-threading Plastite screws to join the sections. Right now for mock-up, I have M2.5 x 20mm pan head screws with a flat washer and a nut holding things together.

Hope to hear from some others,

Here's a couple shots of my hull progress so far, Sections D through G. H is printing now, I just finished modifying Section I and will print that tomorrow.

If it is not too much trouble, do you have a section view of your chamfer joint as my mental picture of your description is not working for me.


I always thought a quarter turn fastener would be a cool thing to try. The slopes tighten the joint in a 1/4 turn. Print the sloped slot on one piece and the knob is the only loose piece.

Just and Idea for experimentation. Thanks for looking.

Sorry for the delay!

Here's a couple shots of the hull section joint with the Chamfer ring.

I think your concept is valid but at this scale I don't think a printed fastener would survive. Layer bonding is one of the weaker links in 3D printing and the way these are printed I would suspect rapid failure under load.

Have you tried printing any of these connectors and testing them under load?

Thanks for the pictures.
No, I have not tried this.
The fasteners I have come across were solid plastic not printed.
