This version was done when I did not have a 3D printer large enough to make the outer shell. So I did it in four pieces.
1 The original drawing in Fusion 360 (aluminum cuphead, jigger mold with bowl-outside profile, bowl mold, jigger mold case and jigger template).
2 The original bowl purchased at Ikea alongside the 3D printed shell of its outside contours (12% bigger).
3 The plaster model of the outside shape (created using the shell mold).
4 Printing a pair of circular rails (with flanges for clamping).
5 The rail assembly (clamped and soaped) ready for use to pour working mold.
6 Old method: The model and rail assembly glued to an Arborite bat (using sticky clay). Both were centered manually on the potters wheel (we later did this using a 3D printed spacer ring).
7 The light-bulb moment of realizing the rails are not needed! I now print the outer shell as one unit, as thin as 0.8mm. I leave it in place, for durability.
8 The finished working mold with PLA-printed outer shell left in place.
9 The jigger mold inserted into the cuphead, ready for use.

A cereal bowl jigger mold made using 3D printing
A new way to 3D-print your way to making jigger molds and templates. The molds are encased in a 3D printed shell that makes them fit perfectly into the cuphead. And the template is precise and very effectivwe. |
