Flamethower pump needs a gun

thingiverse

This is a flamethrower pump that requires a 67 mm fan. A suitable option can be extracted from a microwave. To complete the build, you'll need 9 mm pipes and two bottles of WD40 or an alternative flammable substance. Printing with a resin printer is highly recommended as it will produce a more robust design; however, a .2 layer high print should still yield satisfactory results.
