if you want to agree to $260 each, including S/H to the USA, i'll order 5 prototypes from your 1st prototype batch right now.
color needed is all-silver.
dimensions are 335mm X 240mm X 69mm [ 5.5L ]
I won't be commitment yet, please be patient until I get at least the first prototype.
For prototypes you have to order one first before making a small batch, no matter how small. If you mess up your CAD files and skip the first prototype, you end up with a costly messed up batch.
I won't go into the details of what it takes to get a small batch made, but note, $260 is what it costs for a single prototype, before inspection, assembly, shipping, not including additional time generating different CAD (industry rate for designer is $25-35/hr), confirming design, negotiating with manufacturer.
