Holds a bic (or scripto) lighter so you can tie it to a string or attach it to a keychain. Use it to thwart lighter theives...A derivative of the bic lighter. Challenges the idea of challenging myself...Resize the stl so that the smallest dimension is about 18.5mm. (When I printed it on my UP! it measured 18.48 x 30.29 x 62.43)People with UP! printers can download the saved up project and not need to worry about resizing. The bic slides right in. Pulling it out quickly produces a satisfying pop! Will not print without support material.
