Bike seatpost light leveller/wedge

thingiverse

Many rear bike lights are secured by stretchy rubber straps that attach to the seatpost, but they often end up pointing downwards, making them less noticeable to motorists. To rectify this issue, a simple wedge is placed between the seatpost and light, angling it back upwards for greater visibility. A lip on top prevents the wedge from slipping out, as wedges tend to do when not properly secured. The design accommodates standard 27.2mm diameter tubes; simply scale up or down depending on your seatpost size requirements.
