Handles

Shape Cast handle molds are for sale. These are two part plaster molds (one for each half of the handle). Symmetric molds (the handle shape is mirrored top to bottom) need two copies of the same plaster mold. Asymmetric molds need two different plaster parts (one for the left and one for the right). Each plaster part needs four 3D printed parts - bottom, two different side walls, and the handle shape itself. For a symmetric mold, the four 3D printed parts can be reused twice whereas the asymmetric mold needs a total of eight printed pieces. These all assume a 13% clay shrinkage rate (so your final sizes will vary based on that). Also note that these molds have features that are very specific in size so the mold parts fit together so scaling the files is NOT recommended.

Just like other Shape Cast molds, you go straight from 3D print to plaster without silicone or other materials.

Symmetric

D Shaped Handle Set

We have a set of 10 D shaped handles with different heights. They range from a final height (H) of 50mm to 100mm (~2" to ~4") measured from outside to outside. They extend out 35mm (1 3/8") but are easy to trim shorter if desired when attaching to your pot. These all have the same cross section profile. See the image for the dimensions.

Asymmetric

Ear Shaped Handle Set

We have a set of 10 ear shaped handles of two different widths (45mm and 55mm) and 5 different heights. Shown above is a handle 55mm wide (1 1/8") and 90mm tall (3 1/2") measured from the bottom where it connects to the mug to the top of the curve. For this handle, the distance between the handle attachment points (untrimmed) is about 75mm (~3"). (The other sizes have a similar change). The ends of the handle are intentionally extended out long so they can be trimmed to match a variety of pot forms. These handles have a cross section profile of 22mm wide and 8mm thick. As asymmetric handles, each requires printing 8 different mold parts (4 for each plaster half).
