Replacement feet for MacBook Pro

The rubber feet on my MacBook Pro fell off. These are replacement feet for the laptop ... you need to print 4 of them.
To install the feet I removed the back cover and glued them in place. As an added measure I used a sodering iron to melt the post of the feet and form a 'rivet'. A better solution would be to modify the part so that it 'snapped' into place and was held by friction ... I did not have the patience for this.
