Hello Everyone!

As for the mechanical work, we are currently trying out silicone casting with a custom mold design to cast the outer casing with food grade + medical grade silicone to accommodate the user in terms of comfortability, safety. 

Below is just a initial, simple mold, which will be 3D printed.  material will be injected into the mold with the top two holes

we will use SORTA-Clear™ 18 Product Information | Smooth-On, Inc. as the first material to try out.
