Mods:
1. Turn you shock-screws round, so the button head faces forward. this stops the screw itself digging into the floor and tearing your tower back. With the button facing forward, you have a 'smoother impact face' which doesn;t tend to dig in as much.

Doubling up on towers is a bad idea: Normally means the tower won't break, but the gearbox top certainly will.

There's no real mods here apart from the top one. Make sure you glue the edges of the tower though, it will stop the tower de-laminating.
