Update: better fitting, FreeCAD source file included for your convenience (sorry for very complex file structure and bad object naming).

Cable guide for a generic motorcycle throttle sold with "DZ Hardware" brand in Finland. Motonet sells the throttle with part number 40-02717, compare with your part before printing.

This part is very easy to lose if you are not being careful with your parts - if you need to print this part, you probably also have to start bagging, labeling and boxing your project parts better. While the throttle is also very cheap, the printed part cost is fraction of that cheap price.

I've printed this in PETG with 100% infill to provide plenty of meat for the cable to dig into over time. Infill percentage is not important, but thickness of the walls against the steel wire is; if you insist printing partially hollow, minimum of 2mm wall thickness is recommended.
