We are redesigning our belt stop lock. The purpose is to get a stronger lock force on the belt. 
We want to see if our changes work better than the original design. The part is made in aluminum. The part can be produced whit either CNC Milling or metal 3D printing.  
Dim: 37/19,5x65mm.
We would like to order five test prototypes. If the prototypes look and work as our desired outcome the potential for a batch order is possible. 
The batch order will be for 50 pieces if the price is right.
