Rocket ship #2 based on Tsiolkovsy's 1914 model.

Rocket ship #2 based on a photograph of the 1914 model made by Tsiolkovsky. Dimensions are based on a drawing from the Spaceship Handbook by Jack Hagerty and Jon C. Rogers.  The stl files are at 1:150 scale; however I printed mine at 150% which is the scale reflected in the 3mf project files. The final scale as printed should be 1:100

I have not been able to find the above photo on the internet. What photos I have seen on the internet look like a more modern interpretation of Tsiolkovsky's model and is found at the Polytechnical museum of Moscow. I really don't think it was made by Tsiolkovsky,

If you're not familiar with Tsiolklovsky's work on the Physics of rocketry I recommend the web site Tsiolkovsky.org  This site is great. It has several of his works in Russian as well as translations in English and several other languages.

Printing: I highly recommend the scaled up version.. I first printed it at the original size and the back side of the rocket body  was real rough with the stair stepping and thin walls. Scaling up and printing at a 0.15 mm layer height was better and but still not great, An even lower layer height and/or smaller nozzle would make for a smoother print but will take much longer. Its a trade off of quality vs patience. 

I used a 0.4 mm nozzle with a layer height of 0.15 mm for the body and 0.2 for all of the rest. I used PLA. The STL files are at 1:150 scale. The project files are scaled up and include supports, good orientations, and layer height adjustments. You may want to further reduce layer height on the body for a smoother surface. The only parts that I used supports on were the stand and the chair. 

I used CA glue to fasten the various parts to the bulkheads. The display part glues to the bottom of the bulkhead in front of the top of the chair. I may drill a hole and add a piece of wire to act as a periscope at some point. I'll add a picture of this if and when I do.
