Seat post varia bike light holder

thingiverse

Varia bike light holder/clamp that goes on your bike's seat post. The model assumes the seat post is at a 20 degree angle with respect to vertical. The part requires a single M5 nut and bolt (I used an M5x15) to tighten the clamp. There is a hole on the side of the part that the nut press fits into (see real world picture). You can tighten the bolt as is with a wrench, but I personally used a printed knob (not included) to allow tightening and loosening by hand. Other varia mount sockets have a lot of extra material that makes supports difficult to take off, and that make the nubs that help lock the light into place not be as flexible. The socket on this model was designed to have the nubs be more flexible to help avoid wear and to have more open space in the mount to make removing supports a lot easier. Attached is also an STL of the socket by itself in case you want to use it for your own designs.
