This mold uses traditional spares (instead of 3D-printed pour spouts on our alternative design). After extraction from the mold the spares need to be cut away carefully, using a sharp fine-bladed knife.
Worried about mixing or tuning your own casting slip recipe? We have lots of help on doing that. As motivation, consider the benefits of mass-producing handles and store them in a wet box with the attachment slip - they will be ready to use whenever needed.
I have long wanted an easy way to make molds for slipcasting handles that mate perfectly to any shape mug (or pitcher, teapot, etc). These are the answer. These shells print quickly to only 11 grams of PLA filament. They peel away from the set plaster with a heat gun to give fine detail and a perfect fit. These use 3D-printed pour spouts instead of a mold spare (printed separately) and enable cutting the joint surface cleanly and accurately before the handle is removed from the mold (a version of this is also available with spares). This is the product of a long development process. This drawing is available on the downloads page.
