I've included the screw so it would keep in place. No need to modify anything to be able to use it.

It should fit on most of hi-lifts that mast is 22,5/50mm, and the handle is 33mm in diameter.

The ‘screw’ is reinforced with M3x16mm fallen bolt.

I've printed it in PETG and it does what it is supposed to.
Need to be careful when ‘closing’ it to not shut it too hard - other than that works well.
