Adagio 42-ounce Glass Teapot Handle

thingiverse

We love our Adagio Teas 42-ounce glass teapot, but its handle is too thin and slippery, making the tea time journey from the kitchen to the dining table with a 3lb glass vessel full of boiling hot water more treacherous than it should be. So I printed a grippy plastic cover for it. Accurately measuring the curve of the handle was a fun project all by itself. I ended up printing a flexible curve measuring jig, fixed it to the outside of the handle with masking tape, measured distances between points with calipers and fit a b-spline over them in FreeCAD. The rest was pretty straightforward. Assembly: The cover consists of 2 halves held together by super glue and 4mm long dowels made from 1.75mm filament. Visuals: there is a visible seam between the two halves, right in the middle of the handle, but it works with the rest of the aesthetic. Happy light-orange color helps, I guess. Durability: The design has so far endured several weeks of 3+ times daily usage with no signs of cracking. The heat from the pot hasn't had any visible effects on the plastic cover. Making your own: let's be honest: this is more of a show-and-tell project. The chances of anyone else in the world owning this particular teapot model AND having a 3d printer AND seeing this build AND saying "yay, let's make this" is close to nil, BUT if you do happen to actually need this thing, please print the teapot-handle-curve-test.stl first and see how well it fits the outside of *your* teapot's handle, before you spend time and filament on the actual thing only to have it not fit because I'm guessing the glass handles are made by hand and each one has a unique shape, and the fit on this design of the cover is pretty tight. Happy to share the original FreeCAD files if anyone wants them.
