MT-07 Throttle Tube Insert

One thing I've wanted to improve on my MT07 is the throttle throw. As standard, it is 90 degrees, which is way too much IMO. I find it awkward and I've heard the bike will feel more responsive with a shorter throw (which makes sense). The youtube overlords tell us that this can be mitigated by installing a throttle tube from an R6, as it has a larger diameter where the throttle cable is installed.

I had a hard time finding an R6 throttle tube online, so I fired up my favorite CAD software and the 3D printer.

The diameter of the stock throttle tube can be increased by inserting a... thing? - don't know what to call it yet.
