This is a modified version of my LCD8 mount for oversized, curved handlebars.

I called Lord of the Rings out of fun because it uses a ring-shaped adapter to deal with somewhat bend / curved handlebars.

For my E-bike with the Kuteng controller and LCD8 I used a bit curved MTB handlebar with has nearly no straight section close to the stem. This makes a really rectangular mounting of any display or light holder nearly impossible. To allow somewhat "angle correction" I designed an adapter ring with a spherical shape (34 mm in diameter). The holder itself has a similar shaped groove which allows you correct the inclided position by a few degrees. I will post some images as soon as I printed this version.

Oh yes, and just as a side note: Be patient if you do the final rendering for the LCD8 mount. It takes ages. Simply get a cup of tea or do something else.
