Are you like me? Did you print the basic hextraction board because you were unsure if the game was going to be fun, find out 100 printed tiles later that it is indeed fun and then decide gutters would enhance it greatly only to realize that using superglue to piece everything together removes the possibility of reasonably upgrading your existing board? Then I have the part for you!
This is the fancy gutter, with a cutout where the clip would be to allow it to be placed above existing board clips.
Additionally, the tabs that fit into the grid on the sides are chamfered to allow this to be printed with no supports, provided your printer can handle the overhang.
Finally, Zack, if you're reading it, what printer do you own that can't print the tiny overhang of a tile, but can print this ungodly gutter, and in what orientation? what supports? How?
