21305 Maze – Extra Tilt Tutorial

In my previous posts about the LEGO Maze (set 21305), I talked about the imbalance in the tilting mechanism, and mentioned I would be putting together a tutorial on how to modify the official set to extend and balance the tilting capabilities.

Just to be clear, this will not make it any easier to solve the mazes, and is not necessary to enjoy the full awesomeness of the set. I’ve been playing with the unmodified set for the last few weeks, and I haven’t felt the need to modify my own copy yet. That being said, making this modification might expand the range of obstacles that you will be able to build. Does anyone want to try building ramps? It also might make it feel a little less constrained if you have an aggressive play style, especially when tilting the inner frame to the left.

The modification involves raising the tilting frames, so there is more room for them to tilt in each direction, and requires no additional pieces. You just need to move a few pieces around. It’s definitely easier to show you than to explain in writing, so follow along with the video if you are interested in trying it out.

One note, this modification will disable the locking feature, since there is now a bigger gap between the tilt frames and the base, so a few extra bricks and plates will be handy if you want to re-enable that feature. The modification raises the tilt frames by the width of a one stud brick, which, if you know your LEGO dimensions, is 2 and half plates. In the video I show you one option for re-enabling the lock feature, which is to split the difference and increase the height of the locking block by 3 plates (1 brick) and the height of the ball container by 2 plates. If you are ambitious you can increase the height of each by 2 and half plates by using some fancy building techniques with bricks with studs on their sides.

The picture below shows the unmodified set on top and the modified set on the bottom, which might give you a better idea of what this change will do.
