Original description from Thingiverse model:
I printed mrclauds Motorbike Cruise Control but it never stayed enough to go over bumps and whatnot, I remixed it into this. It allows you to put rubberbands on the front and backside, a nice bonus is the little hook lets you press your thumb on it and release the throttle lock without actually closing the throttle, also the hook can be used as a thumb paddle like on an ATV to remove strain from gripping the grip without actually using the lock.
I printed this with 50% infill and 4 walls so that the joining sections are 100% walls.
The author remixed this model.
I added one (two) more sections to stiffen the part as the fitting on my throttle grip was too loose and I don't want to add the rubber band to alleviate that.
