I needed a mounting solution for a Büchel LED e bike backlight and this is what I came up with.
Printed mine from black Das Filament PETG.
Useable for saddle posts with 27mm diameter and LED backlights with minimum 48mm screw post distance.
Requires three heatset inserts M4x5 or M4x6, two M4x16 screws for the clamp and one M4x30 (or longer) screw to lock the pivot.
F3D source file is attached if you want to make modifications.
The author marked this model as their own original creation.
