It’s a bit hard to justify a 3d printer for a single project, but if you think you’ll use it for other projects then that’s the way I would go. I just finished putting together a bit of a Frankenstein 10" rack based around these printables.com/…/1564648-rail-with-integrated-cap…

Biggest callout would be to make sure the printers you’re looking at have a large enough bed size to print the model you land on. The original one I was planning on printing couldn’t fit on my printer.
