CadetThrottle: Slim/throttle only + 3dPrinted Spring

I really liked Vince_Prints' throttle design but I didn't want to spend the money on buttons and a key-switch as I don't really need them with my set-up. I've basically just cut the top half off. I was sort of forced to just trace over his design in Fusion so it's not the exact same but the dimensions are accurate and I've printed a working model. I have also included a working 3D printable spring. I've printed it out and plan on using it for the life-time of this throttle. Please let me know if you have any questions regarding this design or if there are suggestions! Great design Vince.
