Summary

Edit 1/24/2020: New version available. Needless to say, I think it's better.

This is a variation of my previously published drop bar dropper lever.

Improvements include:
higher cable housing entry puts it closer to the bar
angled back cable housing entry
slimmed down rear lever underside

It still uses the same brake/shifter bar clamp and 608 bearing as the previous part, so refer to that project for more information.

As mentioned in that project, build with high infill. Supports may only be necessary on the bed.

Routing the housing and wrapping the bar isn't that much of a pain, but I had to wrap a couple of turns of the bar tape underneath the cable housing when wrapping around the part and brake lever.

This also has not been tested on the road/trail yet, I am still making other modifications to my bike.
Update: works well from the goods, but interferes with the grip in the drops. I was worried about it interfering with my fingers if it's lower down, but considering it's on the inside of the bar, my fingers will get a decent amount of wrap around the bar, so I'll redesign this to sit lower on the bar, not nestled right up against the brake hoods. I want to angle the housing entry more towards the bar so my thumb doesn't have to wrap around it so far. Basic changes have been started, but my day job is getting in the way :/
