This simple mechanism alternates between sending balls left and right. It's one of the most important tiles in Hextraction, the hackable, 3D-printable board game.

Print one Tile and one Flipper, ideally in PETG or nylon. Insert an M3x8 or M3x10 screw in the flipper, drop an M3 washer onto the tile, align the peg on the flipper with the slot on the tile, and screw it down. Make sure the flipper spins loosely and freely - it might need a touch of grease.

I also snuck in an Advanced version with more entrances. It's more versatile, but also more complex. I recommend printing the basic version first, then upgrading to the Advanced version later.

All of my Hextraction tiles have a built-in sacrificial support under each notch - remember to snap it off after printing. Enable the brim if these detach from the bed.

Hextraction is a 3D-printable, modder-friendly board game designed by me, Zack Freedman of Voidstar Lab. In addition to tiles, you'll also need 10mm steel balls or 3/8" slingshot ammo and a game board. To learn the rules and how to get started, watch the Hextraction video!

Hextraction is absolutely free - it's free of charge - all of my models are here on Thangs, commercial use allowed. It's free-form - you can play with any number of opponents, even zero. It's free to modify - you can create your own tiles and configure your own board.
