I designed this as a birthday gift for a friend that's into cigars since some people say it's less bad for you compared to butane. It's also really useful for doing heat shrink tubing on electronics since it's safer to use a hemp wick than to hold a butane lighter on.
This lighter has a built in spool to hold a hemp wick. I've included 2 small test pieces so you can print both first and test on your lighter to see which fits best. I would recommend the looser version and then wrap a little bit of tape around the lighter to get the right fit since my printer was being a little inconsistent on the hole size. Print the lighter upright with the spool side down.
