1. Separately mold and pour all hard pieces of toe (5 total-case, 2xslider, 2xtoes w/ spines)
2. mill out cavity and fit pieces into place
3. fasten pieces either with wax or by some other means
4. pour soft flexures
5. extract

• make slider c channel part taller to decrease likelihood of binding (creates less point like contacts at the walls

• use curved flexures--will provide nonlinear response, but allow for more travel and more compliance
• ensure that the slider radius on the corners is larger than the channel radius, prevent getting stuck
• continue using .05mm gap for sliding--equivalent about .002in
• possibly use a thin backing to separate toes, prevent neighboring toes from interacting, complicates manufacture however
• bench level tests of flexures to test compliance and design with 1,2,3, or 4 small flexures
