Snow blowers, and other forms of "gardening tools", use this stupid plastic key in order for the machine to work. I lost mine and luckily I found a make on Thingiverse. This is my remix of it in order to remove the need for support as well as adding a hole to be able to attach it to the machine.
I used PETG and an infill of 25%
