solidoodle base washer for aluminum bed

thingiverse

Noticed that the tiny openings at the bottom of the aluminum framework are actually 5mm while the screws being used to hold everything together are only 3mm in size. The back edge of the framework occasionally drifts sideways. Going to give these observations a try and see if they can help minimize the movement. Additionally, the nuts securing the screws to the print bed have a tendency to come loose over time. This is also worth investigating.
