I’m not using that for pla. When printing with pla i just used 210. Im now printing with colorfabb XT filament which is supposed to be printed at 250 celcius.
Also, for a z button i’ll be using a tiny button EDIT: next to the r button, but its hole will be drilled in. The airflow in the final case will probably be just fine since the fan takes in air from the bottom and then blows it out the side (using an air duct) into the holes on the bottom. The port on the bottom is for the nintendo swiitch proprietary dock connector
( ͡° ͜ʖ ͡°).
