I finally put together the 3D printer I bought, and decided to take some pictures of the two that came with the printer.


The most dinged up one was already installed on the extruder unit, the other was a spare in a separate plastic bag.


Here is the vendors website for replacement nozzles: https://www.creality3dofficial.com/products/24pcs-brass-mk8-nozzle-print-head-for-cr-10-ender-series
