+## ENCLOSURES
+
+This board does not have a "full closed" enclosure, because it needs a lot of air flow while stressing it with a lot of output current. So actually the "enclosure" will consists in two pieces: a simple flat base to screw to YULC with 3 M2 screws and the fan holder, that will be connected through one of the screws

+
+> [!WARNING]  
+You can print the fan holder in PLA, but for output power >40/50W, I heavily suggest to switch to ABS due to the high temperatures of the component, otherwise the fan holder can deform bending the plastic
+
+
+The base has two more holes for M2 screws that can be used to design other types of support, like a din-mounting bracket, taken from [thingiverse](https://www.thingiverse.com/thing:2613804) and modified a bit.
