The Vertex Nano is tiny, with a 3″ square bed, but there are plenty of projects you could print on it. Print quality is generally good, with no problems using the default settings. The print surface is unheated BuildTak, so you’ll likely want to stick to PLA.
The recommended slicer is currently only available for Windows. You can use another, but make sure your endstops are set up correctly. There’s no bed leveling, no extruder fan, and the printer doesn’t move away from a finished print.
Take It to Go
Aside from the fan, most problems could be fixed in firmware updates. We tested an assembled version — if you’re building your own, it may take some time to calibrate correctly. Still, a printer you can literally fit in your toolbox seems like a great option.
