If you've ever needed to fix anything in the underbelly of your SmartrapCore (like checking wires, or trying to find that damn tiny M3 nut that accidentally felt somewhere in there), you know how annoying it is to have the printing plate falling on your hands. I've already designed a plate holder to resolve this (http://www.thingiverse.com/thing:815843), but it was before I started using Andreas's new Z system (http://www.thingiverse.com/thing:896556), which is really great, but can't benefit from that so useful little hook. So… I designed a new one, that can be used with the new Z, yeah! :)Beware : this new accessory is extremely difficult to use… Instead of hooking it up on a X axis bar, you'll have to use one of the Y axis bars. Yeah, I know, nobody could have ever guessed that. That's why I put it in the instructions part. ;)
