Prusa Mini Heatbed Cover Fix

SCALE TO 10%\r\n\r\nChris Warkocki spotted an issue with the Prusa Mini heatbed.\r\n\r\nApparently, Prusa decided to wire the connectors through the screws on the bed on the mini. This means the connector is powering the bed by passing current through the screw and pad underneath instead of attaching it directly to the pad. With very little surface contact from the screw, and a cheap steel alloy screw that's not a true conductor, there's a fire risk due to higher resistance of the screw.\r\n\r\nThere could also be a larger than necessary current draw by the bed to hit its desired temperatures. I took the Prusa Mini files from the Prusa3D website, modified them to fit the connectors on top, and removed them by unscrewing the screw. Then I moved them to the top and screwed them back down. It doesn't fit perfectly but close enough - provides the protection necessary without increasing the height of the top piece as it would hit the heater block.\r\n\r\nIt seems like some people are having trouble. This fix involves moving your connectors to the top, so they're in full contact with the pads on the heated bed. Get them up there!
