Strengthened Brompton Front Carrier

thingiverse

Hi, thanks for coming here. This is my first public design. I remixed this from Brompton Front Carrier by Altrome after testing with various failure modes. I've settled down on this strengthened design that has become quite reliable for my daily use (laptop in bag with tools and water bottle). I found that the earlier design tends to break at the Support because the structure is too minimized. I've improved the design at the bend which results in stronger load bearing capability. Another weak point is when you make a sudden turn while cycling with a loaded bag - the carrier will have inertia in the initial direction and result in breaking at the Carrier screws. So I've redesigned the Carrier and the front of the Support to improve the inertial load while changing directions. (capitals refer to the names of the 3 parts in this Thing) So far it's the only 3D printed design that has survived cycling over road bumps with that load. Obviously, it is not as strong as the original or metal versions. If you know of another way to make it better, do share with me in the comments!
