I have an aerosol spray that I use in the garden that is made from concentrate. The concentrate is powerful stuff, so no way I’d like to use stuff from the kitchen to measure it. The top to the aerosol sprayer is also very narrow, so you can’t just use a spoon or other tool to get in there.
The status of the dishwasher has caused more than a few discussions in the household, when one of us assumes that it’s clean when it’s not. To make it easy to know, I designed and printed a simple indicator. There’s a slider that can move to change the status.
3D printing isn’t just for fun, it’s often surprisingly practical. It’s a great tool for putting together little things to address very specific problems that you face around the house, like cleaning out your vacuum cleaner.
