This is a 3D-printable replacement handle for AL-KO clamp bolts (specifically type 643100), often found on trailer jockey wheels and other towing accessories. I use it on my Fendt Bianco Caravan.
The original part has a cylindrical red plastic grip with a rounded end and an internal bore to accommodate a metal L-bolt. This version accurately replicates the shape and proportions, while also being fully parametric in OpenSCAD for easy customization.
