3D model description

Update 2019-07-31:
Added an adapter to attach to the original mount since my printed clamp broke.
Print the adapter standing on its "nose" for best strength and minimal support.
You will need two 17-18mm 3mm screws and nuts to attach the adapter to the original mount.

Headlight mount for 32mm handlebar (just like the original), but adjusted so custom versions of adapters can be easily added.
Requires 3 4mm screws, nuts and a washer for assembly.

I added an adapter for Sigma Lightster with a printed pin to lock the light in place.
The original mount of the light has a small plastic part which has to be bent to get the light on and off the mount.
It tends to break after half a year or so - hopefully the version with the pin will last longer.

I have tested the design printed with PLA for several weeks now and it works very well - I will update the description if something changes.
If you notice any problems with the mount please let me know.
Sorry about the bad picture quality - didn't think about that when printing in black.

Planned improvements:
Currently the pin does not automatically return to the locked position.
A spring (e.g. one of a clothespin) could be used to keep the bold locked instead of the hexagonal part of the pin.
