-3D print ninjaflex filament cage as both structure and mold for silicon casting gripper. -(maybe multilateral? ninjaflex as structure to limit how silicon change shape when blown up, wax filament as mold, water soluble filament as internal structure for 3D shaped hollow silicon casting.)

-test result: Ninjaflax + pla = good, Ninjaflex + scaffold (water soluable) filament = good, wax filament + any filament I have = fail, pla + scaffold = good) -still need to test: wax filament silicon mold de-molding characteristic, scaffold filament solubility when embedded in silicon.
