Designed on Sunday, November 11th, 2018, ordered the same Sunday, paid and made the following Monday, mailed on Tuesday, and arrived on Wednesday. If you ever need something done out of carbon plate, contact Rolf Meichtry at CNC-Modell.ch. He's not just quick; he does some quality work. And all that at an extremely reasonable price. Now I have a light unit that I can just pop on and off the handlebar. My design only works for a Jones H-Bar Loop handlebar, but one could easily design a T-shaped plate to attach to a regular handlebar and stem.
