POTENTIAL COST IMPROVEMENTS

Transition from UHMWPE to HDPE Also FDA compliant and wear resistant Decreases total material cost for one jig by $5

Maybe insignificant

Eliminating T-Slot Total Cost Decrease ≈ $50 Will design new way for table attachment

Potentially Velcro cost per jig ≈ $1

With Improvements Total Jig Estimated Cost (w/wrench) ≈ $242
