Core One Electronics Cover with Fan (No MMU Required)

This cover replaces the metal one on the front of the xBuddy box and provides extra forced air cooling and ventilation, especially in the vicinity of the stepper drivers. It has optional colour text which can either be glued in or printed with an MMU.

Provided are versions with and without the 40mm fan mount.

A cover with text is also supplied to replace the printed cover for the PSU terminals. It has an optional 3mm hole for a short rod of clear acrylic to serve as a lightguide for the power indicator LED.

I suggest printing the upper cover with auto generated organic support set to be on the build plate only. The rest should be printed without support.

I'm not aware of a convenient 5v or 12v pin on the xBuddy, so power options are:

• Get a 24v 40mm fan and wire it to the xBuddy's input terminals.
• Run external power (such as from the 5v GPIO pins on a Raspberry Pi, or a power supply).
• Use a little buck regulator breakout wired to the xBuddy's input terminals.
  There are push-pin holes positioned in the lower cover for a Sparkfun AP63357 5V buck regulator, which is the solution I used with a 12v fan, so it's quiet but has adequate airflow. The pins should be a decent friction fit, but add a dab of superglue to the holes if you want to be sure.
