Prusa i3 Pro B Bed Bracing

This part is designed to remove the sideways movement of the print bed on the pro b, We have all been there at some point, 5 hours into a 6-hour print then someone knocks the table the printers sat on and the print shifts.... ARGH!!

As seen in the photos these are designed to be either screwed in with m2.5 bolts or if you don't want to drill into your printer they can be pressure fitted (that's what I've done and they hold in place with no problems), they go between the threaded rods on the b
