Seatpost mounting bracket for rack mount bicycle lights

thingiverse

The mounting bracket enables bicycle lights that are intended for either dynamo or battery operation to be installed on a bicycle's seat post, provided there isn't a rack. Standard mounting hole spacings of fifty and eighty millimeters allow for typical bicycle lights mounted on racks to fit neatly onto the seat-post. The bracket stands out as unique due to its need for just one metal bolt for assembly, which simultaneously presses the bracket against the seat post while holding the three distinct printed components together securely. To get an optimal position, adjust the light's angle before tightening the bolt.
