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 https://www.printables.com/model/1564648-rail-with-integrated-caps-for-10-inch-rack-system https://www.printables.com/model/1173672-10-mini-rack-all-3d-printable

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.

I understand unplugging a second monitor to try and get the cleanest data possible, but Id be super interested in the data with the other monitor plugged in and even playing a video in the background.
