Update 2/4/23 - Added a variation with a rounded end and flat top. It should be printed upside down, and eliminates the sharp edge at the bottom that could cause irritation during use.

I measured the important bits and then made two versions of a two-finger trigger that fits the slot.it SCP2 and SCP3 slot car controller handles. If you lost or wore out your original trigger, print one of these to replace it. You will need the original screw and nut to secure the trigger to the handle.

Printing in the provided, vertical orientation is ideal. No supports needed, and you don't really feel the layer lines. I printed mine in PLA, but any material should be fine.
