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 we printed a grippy plastic cover for it. Accurately measuring the curve of the handle was a fun project all by itself. We 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.
