For easy mixing of tea cream without spilling. Requires an Ikea $3 battery-powered milk frother and a small Ikea fork (Dragon dessert fork). The fork prevents the liquid from rotating too fast and spilling over the cup. The printed part doesn't come into contact with the liquid.
For 3D printing, I recommend using dry PETG printed at a higher temperature for better layer adhesion.
Assembly requires a bit of force to insert the frother and the fork. Pay attention not to break the print or cause injury.
Let me know on the Discord server if you have improvement ideas for the design.
