Quick model for holding my BIC lighters using Miss Adventure's 1x1 template of Zack Freedman's Gridfinity system. (https://thangs.com/designer/Miss%2520Adventure/3d-model/Gridfinity%2520)

It's my first model. It only loosely fits them, but it holds them nicely for my shelf so I don't constantly misplace them. I've had a few comments that only their mini lighters fit. All the ones I own do (I wouldn't call them mini either, but hey maybe they are), so take into consideration. 
If mine doesn't work, or you don't like the design, check out this mirror one done by @TomieM that has chamfered edges (https://www.printables.com/model/284679-bic-lighter-holder-gridfinity-1x1)
