Antigravity Marble Game

thingiverse

Based on the classic game "Shoot The Moon," this compact version offers a fun challenge for players who enjoy marbles or steel balls - sizes like 15 and 20 mm work great. An STL file comes with it, allowing you to easily scale it up if needed. A notable feature of the control rails is their rectangular cross-section rather than square, which makes it easy to adjust them by 90 degrees for different marble sizes. Initially, I considered drilling holes and using pins to attach the far ends of the rails, but decided to simplify things by making this version "print and go." This design is especially suitable if you don't need supports (see below).
