Gem of Truesight
thingiverse
Great for detecting your impending doom from being surrounded by Riki, clinkz, Nyx, Broodmother, and Templar Assassin. I used a low-cost little aquarium rock which should be essentially standard size but I also included a printable "gem". The alignment holes I believe are the size of 1.75mm filament but they're not entirely necessary
