Angled filler for bicycle seatpost lights

cults3d

I've got a stash of tail lights for my bikes, some are really top-notch (any of the Bontrager lights are truly exceptional) and some are pretty budget-friendly. The high-end lights attach to the seatpost at an angle so that the light shines parallel to the ground, which maximizes its visibility from behind, but the affordable lights mount parallel to the seatpost, pointing downward. This significantly reduces their brightness as seen from behind since most of the light ends up on the ground behind the bike. I don't always have my top-quality lights with me when I need one, so I came up with this design that fits a 27.2mm seatpost and tilts the light to point level, making it more visible from behind. It will fit a larger seatpost, though it won't follow its curve as smoothly. Note: The green light in the photos is 10mm taller than the supplied STL file because I discovered it was too tall. If you need it taller, I've included the Fusion360 F3D file, or you can reach out to me and I'll upload a taller STL if needed.
