I vape so I got tired of buying glad tubes whenever I would drop my value so I printed a replacement "glass" it worked for years. The other useful thing was replacement keys for my old keyboard, the A and G keys in the pic. image
One of the most useful things I've ever printed, was a wrench to take apart small valves for cleaning on a breast milk pump for mom. Got the file off of thingiverse. #dadlife #breastmilk
