Sharing another project I've been working on, a titanium front carrier block with a reinforcing top collar that wraps around the headtube. Essentially eliminates the risk of the front carrier block bolts breaking in the frame from an overloaded bag.
Inspired by Eerder Metaal's Full metal bracket, I wanted to make one that was lighter but still stronger than the standard block. Objectively it is weaker than his but it's strong enough to prevent the bolts from breaking since the top collar redistributes some of the load on the two front bolts to the head tube of the frame. And being a weight weenie, the fact that mine weighs 71g compared to his at 198g (standard block is 100g) means I also save weight!
I've been using a V1 prototype for several months now and it's held up perfectly and I've implemented some changes; better fit, more clearance for the lower bars by extending the bag mounting about 1cm outwards.
I made a video that talks about the design process, how it's made and how it's installed: https://www.youtube.com/watch?v=_SmHuC7lvfw
This was fun to design and the first time I've designed something for laser cutting. Unfortunately i had hard time even getting a quote from a UK company to have these parts made, maybe because the project is too small or I sounded inexperienced (which I was) so I had to get the parts laser cut by a company in China. But the assembly was all done in London so maybe I can claim this is made in London, UK, just like the Brompton?
I have a few more projects lined up using titanium 3D printing so looking forward to working on that now.

Good work OP, getting stuff made in England can be….well complicated I know from first hand experience it can be done just takes some time.
As to your question, it’s not made in London though so that would be very desengenuous potentially illegal as far as from a business perspective is concerned as Bromptons are hand welded in England. You could however say British designed and assembled.
