Hip flask funnel

thingiverse

Simple funnel for easily filling a hip flask. Other designs had spouts that were longer than necessary, so designed my own simpler and smaller design. The spout is 10mm wide, as my hip flask has an 11mm tube. 3D printed items should not really be used with food or drink, as the many layers provide an excellent surface for bacteria to grow, and are pretty much impossible to get clean after a single use. As such, either plastic wrap this before use, or treat it as a single use item. I'd feel bad saying it if PLA wasn't biodegradable or so cheap.
