Notes on scaling and working with Blender
My target scale for all source files and output STL files is 1:1000, However, I generally recommend 1:2500 or smaller given the detail level of the model. Although these files have not been extensively tested through printing, they are intended to be resized to match common modelling and miniatures scales.
Target scale - Scale STL files to: - Notes
1/3900 - 0.25641026 - FASA miniature scale
1/3788 - 0.26399155 - ADB Starline 2400 scale
1/3125 - 0.32 - ADB Starline 2500 scale
1/2500 - 0.4 - The Trek modelers "Golden scale"
1/1600 - 0.625 - TOS 3-Ship Set scale
1/1400 - 0.714285714 - Common resin model scale
1/650 - 1.538461538 - Modelling scale
1/537 - 1.862197393 - Common scale for TMP models
1/350 - 2.857142857 - Large scale
Blender
Blender is free, which to be honest was the primary factor in my decision to learn it. There are many fine video and text tutorials available online if you're interested in learning more. For a basic tutorial on moving and joining objects in Blender(which should be the minimum you need to know when working with these parts), see this instructables tutorial.
You can use File -> Import -> Stl (.stl) and File -> Export -> Stl (.stl) to load or save STL files in blender.
Note: This kit was built using Blender 3.1.
Post-processing STL output
Although all of the STL files included have been tested as valid watertight meshes, joining the parts together and exporting new STL files can introduce small errors that may cause issues with slicing programs. I recommend any STL files you create are checked using a program like Netfabb Basic free edition. Doing a simple "Close All Holes" repair has fixed most of the issues I've run into so far. If you do run into issues with mesh quality, please let me know.

Parts
The rom-noncombat-parts-stls.zip file contains all of the part STL model files listed below. Note that part files are not meant to be printed on their own, but instead they are meant to be combined to create new ship designs that can then be output as joined files and printed.
