# 7.1 3D printing elements

For this stage you'll need:

{% hint style="info" %}

* Print parameters tested on Prusa i3 MK3S with a 0.6 mm nozzle. 
* The default ESC compartment fits ESCs with a height of up to 34 mm (which covers most water-cooled ESCs)
* If you don’t plan to install water cooling, separating the ESC and electronics compartments isn’t necessary — the alternative cover functions more like an electronics tray in that case
  {% endhint %}
