This mod replaces the existing channel at the top of the building with a custom 3D print. Unlike the stock channel, this mod prevents the balls from going STDM while making the path a little more interesting than a straight line. The mod also comes with additional pieces that fit into the top of the print to cover up the screws to make the building a little more seemless.
Two variations are offered, a smooth top and a rough top.
Looking for a custom screw cover? Let me know and I can see what I can cook up


Installation is easy:
1. Remove the existing channels at the top of the tower with a Phillips screw driver.
2. Carefully remove the screws and plastic standoffs from the existing acrylic.
3. Carefully snap the standoffs into the new top parts.
4. Put standoffs through holes on the main roof piece.
5. Thread screws through the holes and screw it into the tower.
6. Snap the screw covers in place.
7. Destroy that building!
