This was designed for my beta version Smoothieboard. I have uploaded a stretched version to suit the X4 and X5 production models, however I do not have one of those boards so consider that model to be UNTESTED. If someone can print one and try it out for me that would be great =D
Note it was intended to work with vertical connectors not plugable terminal blocks like I have seen on some boards. I have allowed a bit more clearance for the X4 X5 version, however I cant confirm if there is room for plugable terminal blocks until someone tries it for me.
The slots in the lid should be over the drivers, the rising hot air is what will pull fresh air in at the back.
I printed it with 2 shells and 50% infill. Weighs about 85g I think with both the lid and the box.
Carefully drill out the holes with a 2.5mm drill and then tap them M3.
Be gentle tightening the screws, its only plastic!
