Brompton Front Carrier

This is the first operational prototype of the custom front carrier block for my brompton. Previous versions were so fragile, but this version seems to work. Must be tested and, for sure, modified...
You must use 3xM3 **metallic inserts** in order to assemble all the parts. All the inserts are placed in the support part.
