I want to install a heated bed MK2a and an extern power supply. I would like to mount the power supply like the one from Velleman.
For that I need to drill some holes in the Vertex case.
The only thing I am afraid of is that the plastic maybe splintered?
It is rather safe to drill holes, just drill with lowest speed available and low pressure. The trick is to not get the plastic to hot that it melts. Clean the drill often.
To be aware of splintering when you drill in soft materials put a piece of wood or same material after de place where you drill and drill through both pieces, you only have splintering on the last piece you drill.
