Beta Clutch lever - extended

This is an extended version of @gperuch 's clutch lever. I printed that one out, tapped the threaded hole, and it worked as designed on my Beta 300 Factory Evo.

However, it was too short for me and I would have to move my clutch perch out to reach it - limiting my mechanical advantage.

So, I made it longer. My plan is to just have it as a backup if my current lever breaks during a competition. It's probably not as strong as the aluminum version - but I can have several backups just in case.

I also moved everything to be flush across the top of the lever so it'll print upside down without needing supports.
