Solved: Replace ugly and obstructive alternative design from JJP!

Clear. Simple. Works. No instructions. No extras. Just the piece of 1/8" laser cut acrylic as you see in the photo of my game.

This is a reverse-engineered version of a part sold by PU-parts.com - who, unfortunately, won't ship to the US. If you live in Europe (or somewhere else PU-Parts.com ships to), don't bother me :-) Go get the original!: https://pu-parts.com/willy-wonka-ramp-plastic
