This plotter is an open design, CAD and STL files are available here: https://www.printables.com/model/1174835-extruxy-corexy-remix-of-extruh
Brushless servo like the one I have here (not the store I bought it from!): https://www.aliexpress.com/item/1005009176623579.html
(I have not yet uploaded the new servo mount, I don't know how to share the DC-DC converter board I soldered up so until I work that out I'm holding off - I don't want anyone to break their plotter board)
